Growth and optical properties for CdSe thin film by Chemical Bath Deposition Method

Chemical Bath Deposition 방법으로 성장된 CdSe 박막의 광전도셀 특성

olycrystailine CdSe thin films were grown on ceramic substrate using a chemical bath deposition (CBD)method. They were annealed at various temperature and X-ray diffraction patterns were measured by X-ray diffractometer in order to study CdSe polycrystal structure. Its grain size was about 0.3 ${\mu}m$. Hall effect on this sample was measured by Van der Pauw method and studied on carrier density and movility depending on temperature. We measured also spectral response, sensitivity($\gamma$), maximum allowable power dissipation and response time on these samples.
