The electrical conductivity sigma, Hall coefficient R(H) and thermoele
ctric power Q of thermally evaporated CuGaSe2 thin films with differen
t thicknesses have been measured at temperatures between 80 and 480 K.
These properties were also measured at room temperature for thin film
s with different growth conditions. All investigated films are p-type
over the whole temperature range. Electrical conduction was studied in
order to establish its mechanism. The effective mass m was found to
increase with increasing temperature, as a degenerate p-type semicondu
ctor.
