Abstract

The paper reports the detailed analysis of photoconductivity and photo-detecting properties of vacuum deposited zinc selenide (ZnSe) thin films. The vacuum deposited ZnSe films were found to have high absorption coefficient and showed peak photo-response at 460 nm. The photocurrent and photoresponse time of the films were measured as a function of substrate temperature and annealing conditions. Considerable increase in photocurrent and much faster photo-response was observed in films deposited at high substrate temperatures. Annealing at moderate temperatures also improved the photoconductivity and response time of the films
