The proposed absorber can be used in the ultraviolet (UV) region, the violet (V) region, the near-infrared (NIR) region, and the middle-infrared (MIR) spectrums. The absorption rate in the UV, V, NIR, and MIR spectrums is 88.8%, 94.2%, 92.8%, and 89.2%, respectively. After final construction, the created structure has an average solar radiation rate of 92% throughout all four zones. At the 800 nm bandwidth, the absorption rate reaches more than 97%, and at the 1500 nm bandwidth, the absorber is above 95%. Step-by-step building and resulting absorption rate (A), reflectance rate (R), and transmittance rate (T) can be explored in each step. The solar radiation with the respective bandwidth range and AM 1.5 situation can be studied. The parameter converting of the ground layer width and ground layer thickness, the substrate layer thickness, and the resonator layer can be studied. Transverse electric mode (TE) and transverse magnetic mode TM can be studied by converting the degrees from 0 to 50° by 10° separation. The quantity of the electric field intensity in color variations can be illustrated. The comparison table of the current absorption rates of the other published works can be presented.</p></div>","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"19 2","pages":"631 - 641"},"PeriodicalIF":3.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41336009","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 study investigated the influence of laser energy on various characteristics of the fabricated devices, including their optical, morphological, structural, electrical, and photodetector features. The X-ray diffraction results indicate a dominant broad diffraction peak at 69.14°, and the ZnO phase aligns with the hexagonal wurtzite structure. The field emission scanning electron microscopy micrograph illustrates that porous silicon has a sponge-like fashion, while ZnO nanostructures have spherical grains distributed randomly and grow larger with laser energy. The optical characteristics of the manufactured samples were examined using techniques that include UV–vis absorption spectroscopy, UV–vis diffuse reflectance spectrometry, and photoluminescence spectroscopy. The findings indicated that decreased laser energy led to a blue shift in the energy gap. The reflectivity of the produced samples decreased after the deposition of a zinc oxide layer over porous silicon. The photoluminescence examination showed the presence of four distinct emission peaks, namely, UV, violet-blue, blue, and green, consequent to coating a ZnO layer onto the porous silicon substrate. Fourier transform infrared spectroscopy confirmed that ZnO thin films deposited on porous silicon cause surface oxidation and produced a new peak at 455.2 cm⁻¹ related to the Zn–O stretching band. The current density–voltage properties of the fabricated devices in the absence and presence of white light were investigated as a function of laser energy. The ZnO NPs/PS/n-Si photoreactors displayed rectifier features and had outstanding spectral responsivity from ultraviolet to near-infrared.

Herein, the cosh-Gaussian (ChG) laser beam propagates perpendicular to the length of carbon nanotube arrays and is mounted on a planer surface. As the high-power laser beam interacts with the carbon nanotube, the electrons associated with it might be excited, undergo the ionized state, and formed the preformed plasma. By the result, the electron cylinder is displaced with respect to ion cylinder. The laser electric field produces the electrostatic restoration force due to the excursion of electrons with respect to ions. This restoration force causes to arise of nonlinearity. An analytical expression of effective nonlinear absorption coefficient of the cosh-Gaussian laser beam is derived. The absorption coefficient is resonantly enhanced as the laser beam frequency approaches near the surface plasmons frequency <span>(omega sim {omega }_{mathrm{pe}}/sqrt{2})</span>. The presence of collisional frequency between electrons and ions leads to strengthen the absorption process. The laser beam decentered parameter associated with hyperbolic cosine term is a sensitive and effective parameter. This parameter much affects the effective absorption coefficient.
