The LDHs were then subjected to a series of characterization techniques, including X-ray diffraction, Fourier transform infrared, diffuse reflectance spectroscopy and impedance spectroscopy. Thermal stability of LDHs was monitored using X-ray diffraction. It was demonstrated that increasing the iron composition allows for enhancing the process of absorbing light, increasing the refractive index, and inducing a red shift at the absorption edge. In addition, a correlation was found between increased iron composition and a reduction in optical gap energy. However, at high frequencies, the electrical conductivity and dielectric constant increased with decreasing iron content, while the dielectric loss parameters were found to be relatively dependent on both frequency and iron doping.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 3","pages":"225 - 238"},"PeriodicalIF":0.9,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564568","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, attaining remarkable physicochemical properties remains an important aim. In the present paper, we report this aim by studying the influence of cadmium sources Cd(CH3COO)2, CdSO4, and Cd(NO3)2, rarely reported in the literature, on these properties. CdS films were synthesized on glass substrates, at 75°C, via chemical bath deposition. XRD analysis of prepared films indicates that the dominant structure of CdS thin films was hexagonal with a (002) preferential orientation in all samples. The lowest thickness (864 nm), highest crystallite size (95.88 nm), lowest deformation (1.04 × 10‒4) and lowest density of dislocations (1.08 × 10‒4 lines × nm–2) were found using Cd(CH3COO)2. Raman spectra showed that the greatest asymmetry of the peak located at 306.42 cm‒1 corresponding to the fundamental vibrational mode (1LO) and attributed to the Cd‒S chemical bonding, was observed for CdS films prepared from CdSO4 and Cd(NO3)2. This result meant that the defects concentration was higher using these two sources than using Cd(CH3COO)2. Furthermore, the optical results of CdS film prepared from Cd(CH3COO)2 exhibited the largest band gap (2.42 eV), lowest Urbach energy (133.21 meV), and highest transmittance (85%) in the visible wavelengths range (300‒800 nm). The extinction coefficient and refractive index were also affected by the cadmium source. Our findings demonstrated that Cd(CH3COO)2 is the best cadmium source compared to CdSO4 and Cd(NO3)2 to enhance the physicochemical properties of CdS film and make it perfectly suitable for use as a window layer for photovoltaic cells and optoelectronic devices.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 3","pages":"214 - 224"},"PeriodicalIF":0.9,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564567","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}

Ellipsometric measurements and ab initio calculations demonstrate that the α‑In2Se3 crystal behaves as an indirect-bandgap semiconductor with an approximate bandgap of 1.0 eV. Analysis of the density of states, projected onto atoms, shows that the valence band maximum primarily arises from the p-states of Se atoms, with a minor contribution from the p-states of In atoms. In contrast, the conduction band minimum mainly consists of the s-states of In atoms and the p-states of Se atoms. By comparing Raman scattering results with ab initio calculations and conducting group-theoretical analysis, we identified the phonon modes of α-In2Se3.

The synthesized crystalline powder was characterized by X-ray diffraction (XRD). The XRD studies explain that zinc oxide nanoparticles have a single phase with a wurtzite hexagonal structure. The theoretically calculated lattice parameters have obtained using the famous Scherrer equation and agree well accordance with the standard JCPDS card number. Various relevant physical parameters such as micro-strain, stress, energy density, and crystalline size have calculated by using the modified Williamson–Hall (W–H) assuming uniform deformation (UD) model, uniform stress deformation (USD) model and uniform deformation energy density (UDED) model. The root mean square (rms) lattice strain (leftlangle {{{varepsilon }_{{{text{rms}}}}}} rightrangle ) theoretically calculated from the interplanar spacing and strain estimated obtained the USD and UDED models are different due to consideration of anisotropic crystal nature. The obtained results shows that the average particle size of zinc oxide nanoparticles from Scherrer’s formula and the W–H method are the best intercorrelated. All the calculated physical parameters from the Willamson–Hall plot are tabulated, compared, and found to match well the value of bulk zinc oxide.

We calculate the dispersion relation and transmission coefficient using the Green function method based on the interface response theory. The perfect loop waveguide generates photonic bandgaps depending on the number of cells and the structure parameters. The insertion of a defect in the structure generates defect modes inside the gaps. These defect modes can be precisely controlled in terms of frequency and transmission rate by tuning the length and permittivity of the defective segment.

However, detailed theoretical reports on pressure-induced transformations are scarce. We investigated the pressure-induced phase transition, elastic and electronic properties of BaZrO3 under high pressure using first-principles calculations. The findings reveal that BaZrO3 undergoes a series of structural transitions with increasing pressure, shifting from a cubic perovskite structure ((Pmbar {3}m)) to an orthorhombic structure (Cmcm), and subsequently to a tetragonal structure ((I4{text{/}}mcm)). These transitions occur at pressures of 3.5 and 20 GPa, respectively. The calculated transition pressure from Cmcm to (I4{text{/}}mcm) structure is consistent well with experimental values, and the predicted Cmcm structure should be further testified by future experimental study. At zero pressure, the mechanical stability of perovskite BaZrO3 is assessed through elastic constants. Additionally, all stable polymorphs of BaZrO3 remain insulating nature under high hydrostatic pressure. This investigation provides insight into the complex pressure-induced phase transformations in BaZrO3 and offers guidance for future experimental investigations and potential applications.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 2","pages":"104 - 110"},"PeriodicalIF":0.9,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143496872","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}
