Diffusion of Zn in CuInSe2 bulk crystals

摘要

Using bulk crystals of CuInSe2 (CIS) grown in an evacuated sealed quartz ampoule, diffusion of zinc in the temperature range (550-700degreesC) was investigated. The computation of the parameters showed a coefficient of diffusion D-Zn varying from 10-(11) to 10(-1) cm(2) s(-1) and an energy of activation of 0.41 eV. The results of optical analysis made on doped CuInSe2 showed that Zn can act as a donor and the energy E-A of the acceptor level was found 23 meV. (C) 2004 Elsevier B.V. All rights reserved.
