I. Georgieva et al., INFLUENCE OF CRYSTALLIZATION ON ELECTRICAL AND OPTICAL-PROPERTIES OF TE-SE-SN AND TE-SE-SN-O FILMS, Journal of non-crystalline solids, 160(1-2), 1993, pp. 105-110
Electrical, photoelectrical and optical properties of polycrystalline
Te-Se-Sn and amorphous Te-Se-Sn-0 films, evaporated by laser beam, are
investigated. The temperature dependences of the dark conductivity an
d crystallization temperatures, 360-365 K, are measured. Changes in th
e photoconductivity, optical band gap and reflection were observed and
attributed to the crystallization processes. These results are discus
sed in terms of existing ideas for amorphous semiconductors.
