Abstract:

Study subject. Porous silicon is a material with great potential for creating optoelectronic and sensor devices that can enhance various technologies and improve their efficiency. It finds applications in lightemitting diodes, photodetectors, solar cells, sensors, and other devices that require high light absorption and emission efficiency, as well as sensitivity to the optical values of the environment. The deposition of tin particles on porous silicon has potential for developing new nanocomposite materials with customised properties for various applications. Vacuum-thermal evaporation is a commonly used method for depositing oxide films. This method produces high-quality thin layers with good reproducibility and controllable properties. Purpose of the work. The aim of this study was to investigate the impact of thermally deposited tin on the structure and composition of porous silicon. Method. Porous silicon was created by anodizing monocrystalline silicon plates (KEF (silicon electronic phosphorus) grade with orientation 100). The original and tin-anodized samples were analyzed using atomic force microscopy, photoluminescence, and X-ray photoelectron spectroscopy to determine their shape, composition, and characteristics. Main results. The following section presents the main findings. According to the results, tin was deposited on the surface of the porous layer as an island film through vacuum-thermal evaporation. This deposition inhibited the oxidation of the porous layer. The nanocomposites of porous silicon with deposited tin consist of tin dioxide, tin suboxide/monoxide, and metallic tin. The application of the vacuum-thermal method to obtain tin films on porous silicon alters the shape and position of the photoluminescence spectrum band and partially increases its intensity. Practical significance. This technique can be used to produce composite materials with improved characteristics.
