The result of photocapacitance measurement on background deep levels in ZnSe is reported.A short discussion about the principle of photocapacitance technique used in this work is presented.In the case that there is only one deep level located within the upper half of the gap and its concentration
N
T
is much smaller than that of the shallow impurity
N
D
the capacitance transient is a single exponential one.In the case that more than one deep levels exist
the transient is a multi-exponential one When
m
=2 the individualΔCi(∞)and Ti can be determined by multi-regression procedure.
