Abstract

ABSTRACT In this study, bismuth-doped zinc selenide ZnSe/Bi single crystals were deposited on conducting glass substrates to study the effects of single crystals’ molar concentration on a variety of properties. These properties were characterised using SEM, EDX, XRD, and UV–vis. The various characterisations were carried out to determine the material’s morphological, elemental, structural, optical, and electrical characteristics. The ZnSe material’s diffraction peaks were found at (1 1 1), (2 0 1), and (2 1 1), while the ZnSe/Bi material’s peaks were found at (2 2 0), (2 2 1), and (3 0 0), which correspond to the angles (26.12°), (31.00°), (37.02°) (51.73°), (62.67°), and (65.83°), respectively. The material showed a smaller nano-grain size that covered the entire substrate, indicating uniform deposition. A band gap energy of 1.55 to 1.72 eV was obtained. ABSTRACT

铋作为掺杂剂对光伏用ZnSe材料合成的影响

在本研究中，将掺杂铋的硒化锌ZnSe/Bi单晶沉积在导电玻璃衬底上，研究单晶摩尔浓度对多种性能的影响。用SEM, EDX, XRD和UV-vis对这些性能进行了表征。进行各种表征以确定材料的形态、元素、结构、光学和电学特性。ZnSe材料的衍射峰位于(1 1 1)、(2 1 1)和(2 1 1)处，ZnSe/Bi材料的衍射峰位于(2 2 0)、(2 2 1)和(3 00)处，分别对应于(26.12°)、(31.00°)、(37.02°)、(51.73°)、(62.67°)和(65.83°)角。该材料显示出较小的纳米颗粒尺寸，覆盖整个衬底，表明沉积均匀。得到了1.55 ~ 1.72 eV的带隙能量。摘要

期刊介绍： Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
