CdCl2 와 InCl3 를 첨가한 CdS 소결막의 전기적 광학적 성질
Electrical and Optical Properties of CdS Films Sintered with CdCl2 and InCl3
초록
Polycrystalline CdS film have been prepared by coating a slurry constiting of CdS, CdCl2, various amount of InCl3 and propylene glycol on glass substrate and by sintering in a nitrogen atmosphere, and their sintering behaviors, electrical properties and optical properties have been investigated. As the amount of InCl3 increases, the enhancing effect of CdCl2 on sistering decreses resulting in a sharp decrease in optical transmittance and an increase in electrical resistivity. The carrier concentration is almost independent of InCl3 added due to the occurrence of chlorine doping and to the compensating effect of indium dopant. Microstructure an optical properties of CdS film, which contain CdCl2 and InCl3 before sintering, can be improved by sintering in a sealed boat.
