Abstract: The influence of electron irradiation with E = 1.2 MeV for electrical, photoelectric and optical properties of single crystals of cadmium sulfide doped indium atoms

Cadmium sulfide belongs to promising semiconductor device carnals used in electronic, optoelectronic and laser technology. tangible properties of CdS crystals is strongly certified on their tough designer. In addition, collectable to a public figure of features, these compounds are increasingly seen as a model material for the study of character reference and structural characteristics of defects in wide-gap semiconductors AIIVIV group. Therefore, great post is the study of the tempt of lattice defects and their complexes (which as well include a dopant) on the physical properties of CdS- single crystals. A well-to-do regularity for ever-changing the defective condition of the samples is exposure of high-voltage particles.\nIn this newspaper publisher investigated the effect of radioactivity by dissipated electrons in electrical, photoelectrical and opthalmic properties of indium doped single crystals of CdS. Single crystals were full-grown at the be for Single Crystals (Kharkov) with melt down specially purified CdS pulverization in an indifferent atmosphere chthonian pressure of 1.86? 107 Pa. indium doping was carried out in the course of cultivation. correspond to the passport data, the soaking up of indium in different samples was NIn? 1018sm-3, NIn? 1019sm-3 and NIn? 1020sm-3. scape of the samples with electrons with energy 1.2 MeV one-dimensional accelerator was on. Crystals irradiated cooled placid nitrogen blue devils and their temperature during ir ray of light did not rise in a higher place 290 K. The dose of radiation was S? 2? 1017sm-2.\nAbsorption spectra (SP) and photoluminescence (PL) spectra were measured on a standard method of ac maneuver using synchronised detection. As examine Yuchi devices used spectrographs ISP-51 and IKS-12. metre of the spectral diffusion of photoconduction (AF) and optical quenching of photoconductivity (FMG) carried the standard method at a constant appal ...
