Yuri, Registration Date 27-02-2014 Organization Faculty of аircraft and space systems NTUU "KPI" popup.description2 By electron beam evaporation of silicon thin-film footage synthesized nc-Si doped with rare-earth impurities of rare earth metals (Y and Eu) in a wide concentration range ( from a few to tens of atm %). Research profile structures obtained by Auger electron spectroscopy confirmed the formation dvohsharovoyi film structure in the case of a high level of doping Eu and Y. This result is particularly important in the study of electrical and optical properties of heterojunctions based on films. The influence of impurity centers that otvoryuyutsya in doped films with the participation of rare earth materials for structural , electrical and optical properties of silicon material. The simulation of the band structure of nanocrystalline silicon and impurity centers with rare earth metals (Y and Eu) films in nc-Si. The analysis of transmission spectra and absorption of silicon films experimentally confirmed model calculations for the band gap and made ??it possible to establish the technical requirements for obtaining a material with a given width of the energy gap . Substantiates the potential for application of the developed materials to create micro-and nanoscale devices such as thin-film photodetectors , solar cells , biochemical sensors, MEMS functional elements . Recommended area of application of microelectronic instrumentation, materials, photodetectors and photovoltaic cells , communication and feedback .
