Temperature dependent photosensitivity of Cu doped CdS thin film

摘要: Structural, morphological, electrical and photoconductive properties of Cu doped CdS thin film are reported here. All the films are formed in hexagonal structure with polycrystalline nature. Cu alters the rods of pure CdS into small grains. Activation energy rises with Cu incorporation in CdS film. Temperature dependent photosensitivity and photocurrent on pure and Cu doped CdS thin are investigated. Cu doped films show quick photo‐response characteristic. Photosensitivity rises at lower temperature in Cu doped films.
