The multipulse local removal of graphene was investigated by atomic force microscopy in combination with Raman spectroscopy, according to the specially developed technique, which makes it possible to implement multipulse laser impact and monitor in situ the nanorelief and surface structure before and after laser irradiation. All modes of low-intensity laser irradiation with energy density in the range of 0.85 ≤ Е ≤ 1.55 J/cm2 had the following features: (i) formation of craters ≈1 nm deep (i.e., through holes in a graphene film, whose diameter depends on the number of pulses and energy density) and (ii) the absence of any explicit signs of thermally induced etching in the Raman spectra of graphene. The mechanism of multipulse low-intensity laser etching of graphene, caused by photostimulated weakening of covalent bonds between carbon atoms and increase in the reactivity of these atoms to oxidation in the presence of ambient oxygen and an aqueous adsorbate, is discussed.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 1","pages":"49 - 58"},"PeriodicalIF":1.1,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147560537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review presents a comprehensive comparison between monolayer and bulk MoS2, highlighting key differences in their structural, optical, electrical, mechanical, and bio-interactive properties. The transition from bulk to monolayer induces a transformation from an indirect to a direct bandgap, significantly enhancing photoluminescence, charge mobility, and surface sensitivity features critical for next-generation electronic, optoelectronic, and biosensing devices. We also explore state-of-the-art synthesis strategies, including top-down and bottom-up approaches, that enable the scalable production of high-quality monolayer MoS2. By synthesizing insights from recent theoretical and experimental advances, this article elucidates why monolayer MoS2 consistently outperforms its bulk counterpart in functional applications ranging from strain sensors and photodetectors to non-invasive biosensors for prenatal diagnostics. The review not only maps the current landscape but also outlines future directions, positioning monolayer MoS2 as a cornerstone material for advanced technologies.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 1","pages":"1 - 42"},"PeriodicalIF":1.1,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147560515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, in this work, a theoretical investigation of propagation characteristics of TGB in a strongly nonlocal nonlinear medium (SNNM) has been conducted. SNNM is well-known for its nonlinear optical response at a specific location, and it can be affected by an electromagnetic field that extends across a large spatial region. The propagation problem is addressed by expressing the TGB fields in SNNM with the help of the extended Huygens–Fresnel diffraction integral formula and the optical ABCD matrix system. To analyze its propagation dynamics, the effects of different configuration parameters of TGB, such as topological charge, waist radius, and propagation distance, are meticulously examined. The diverse cases like as on-axis, off-axis, and asymmetrical Bessel Gaussian beams can be achieved as special cases by appropriately selecting the complex beam parameters of TGB. This work will be helpful to study and analyze the electromagnetic radiation force, scattering and propagation, optical manipulation, computer-generated holography, light–matter interaction, and optical tweezers and sensors.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"34 1","pages":"75 - 84"},"PeriodicalIF":1.1,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147560539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, methods for solving this problem using an artificial neural network, to the input of which a sample correlation matrix of the recorded field is applied, have been developed. The inevitable inaccuracy of the mathematical model of environment makes it possible to train the network on only short paths using the so-called synthetic data, i.e., data of theoretical calculation. This paper considers an alternative approach, where input data are set by the distribution of recorded field intensity in the depth–arrival angle plane. This distribution, constructed using the coherent state method borrowed from the quantum theory, is less sensitive to the environment model inaccuracies than the initial field recorded by the array and the correlation matrix of the field. It is shown by numerical simulation that the use of the aforementioned distribution may expand the range of distances for which the network can be trained on synthetic data.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"33 6","pages":"448 - 457"},"PeriodicalIF":1.1,"publicationDate":"2025-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145847906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, electronic and optical properties of two-dimensional materials appreciably depend on the type of substrate used and the features of the technological process for producing spintronic THz heterostructures, which directly affects the functional characteristics of devices. In this work, a comprehensive investigation is performed to study the effect of the sapphire substrate and standard deposition stages on monolayer WSe2 as part of the Al2O3/2D–WSe2/Co terahertz emitter. The structural quality, optical characteristics, and the presence of mechanical strain in the WSe2 monolayer are analyzed using photoluminescence and Raman spectroscopy methods. Secondary-ion mass spectrometry is used to perform layer-by-layer chemical analysis of the structure and reveal interlayer diffusion. It is shown that the spintronic emitter fabrication process does not alter key properties of TMDs, which confirms that standard technological procedures preserve the functionality of two-dimensional semiconductor.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"33 6","pages":"434 - 439"},"PeriodicalIF":1.1,"publicationDate":"2025-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145847924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of the conventional and complex temporal shapes of laser pulses with identical energies and durations on initiation of dominant material destruction mechanisms and the effect of recoil pressure are investigated using mathematical modeling. The model allows for the nonlinear depth distribution of porosity characteristic of additive metallic materials. It is shown that pulses of complex temporal shape, which combine a long high-energy pulse and a short high-intensity pulse, cause an increase in the recoil pressure much higher than the increase in the capillary pressure. The increase in the recoil pressure in the laser interaction zone initiates an increase in the volume of the removed material and increases the laser processing speed in additive manufacturing of items. The results demonstrate the potential of using laser pulses of complex temporal shape for postprocessing of metallic materials produced on the basis of additive technologies.","PeriodicalId":732,"journal":{"name":"Physics of Wave Phenomena","volume":"33 6","pages":"463 - 467"},"PeriodicalIF":1.1,"publicationDate":"2025-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145847904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
