PARDO, A et al. Study of the Spectral Response in the Visible Spectral Region the ZnSe thin Films. ing.cienc. [online]. 2014, vol.10, n.20, pp.23-35. ISSN 1794-9165.

In this work are presented results in the study of photoconductivity of ZnSe thin films deposited on glass substrate. The effect of substrate temperature on the spectral photoconductivity and morphological properties of ZnSe thin films were studied. The Spectral response appeared between 290 and 500 nm. In the spectral responses were found two contributions associated with transitions labeled , with energy values of 3:35 and 2:80 eV, respectively. The response time of the sample is associated with the morphology of the samples. In the samples prepared at lower temperatures were obtained response times on the order of seconds, whereas the time decreases by one magnitude order in the samples prepared at the substrate temperature of 250°C.
