摘      要：SnO_(2)-ZnO thin films consisting of nanoscale crystallites were obtained on glass and silicon substrates by solid-phase low-temperature *** synthesized materials were studied by XRD and SEM methods,electrophysical and optical properties were evaluated,as well as the band gap was *** was shown that regardless of the phase composition all films were optically transparent in the visible range(310-1000 nm).The nanocrystallites’minimum size,the highest activation energy of the conductivity and the smallest band gap calculated for indirect transitions were shown for a thin film 50SnO_(2)-*** was assumed that the band gap decreasing might be attributed to the existence of surface electric fields with a strength higher than 4×10^(5)V/cm.
