The kinetics of photocnductivity (PC) of undoped and p-doped Zn1-xMgxT
e alloys (0 less than or equal to x less than or equal to 0.4) has bee
n determined by their frequency dependence and relaxation. The electri
cal conductivity of undoped, Li- and p-doped samples was also measured
as a function of temperature in the range 100-300K. At room temperatu
re, a and p (conductivity and. hole concentration) decrease while mu(H
) (Hall mobility) does not vary with increasing x. The results are dis
cussed taking into account the alloying effect and random distribution
of impurities.
