Successful preparation of ZnO : M epitaxial thin films (ETF) in situ doped
with donor impurity M = Ga, Sn by chemical vapor despsition in a low-pressu
re system is reported.
Highly conductive (up to 10(-4) Omega cm) and transparent (T > 85%) ZnO : M
ETF have been successfully produced on single crystal (1012) sapphire subs
trates. Electrical properties of the films as well as their excition lumine
scence were studied. (C) 1999 Elsevier Science B.V. All rights reserved.
