摘要：

Amorphous films of CuInSe2 were deposited on glass substrate by flash evaporation of source materials. The films were found to be p-type semiconductors. The direct optical band-gap energy was obtained to be 1.21-1.41 eV. The film DC conductivity ranged from 1.2-5.7 S cm(-1) at 285 K for different film thickness with corresponding activation energy of 55.5-301 meV. From temperature dependence of conductivity, the carrier transport was interpreted to be due to band conduction above 270 K. (C) 2000 Elsevier Science B.V. All rights reserved.
