The focus of the work revolved around a unique hybrid structure consisting of selenium nanoparticles that were embedded within a polyvinyl alcohol and iron(III) oxide. The examination of micro structure information yielded findings that support the notion that Se nanoparticles have an impact on the structural properties of PVA/Fe2O3.

The design of the cavity involved determining the cavity length, selecting the material for the cavity spacer, and carefully placing the quantum wells within the cavity to achieve maximum overlap with the electric field. In our case, the choice of the dielectric Bragg mirror with SiO2/TiO2 layers helps in achieving high reflectivity and low optical losses. The quantum wells are strategically placed within the cavity to ensure maximum overlap with the electric field. This allows for efficient carrier injection and recombination, leading to laser emission. The specific composition of the quantum wells, In0.54Ga0.46As0.99P0.01 / In0.75Ga0.25As0.55P0.45, indicates the proportions of indium (In), gallium (Ga), arsenic (As), and phosphorus (P) in the material. These compositions are chosen to achieve the desired electronic band structure and emission wavelength. By studying the eigen frequency and internal standing waves in our designed laser cavity, our aim is to understand the resonant modes and behavior of light within the device. This knowledge is crucial for optimizing the laser's performance and improving its efficiency for various applications.","PeriodicalId":49156,"journal":{"name":"Journal of Ovonic Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135614423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effect of bismuth substitution was studied by investigating the structural and magnetic properties in detail. X-ray diffractometer results confirmed the creation of single phase along with a slight occurrence of orthophase in prepared ferrites. Average crystallite size increased from 14 to 28 nm by increase in bismuth concentration. SEM micrographs were in complete agreement with XRD results showing spherical to cubic grains which was a confirmation of cubic spinal structure. Average estimated grain size of 52 nm showing agglomeration was also a good testimony of XRD results. VSM technique was employed to study magnetic properties of prepared samples within applied magnetic field strength of -10,000Oe to 10,000Oe.
