A study of single injection space-charge-limited current flow in insulator
with two sets of traps distributed in energy is presented for a particular
situation in which the energy separation of the two sets of traps is too
small to give rise a current-voltage characteristic with maximum structure.
The current-voltage characteristic is obtained in a simplified way with the
help of regional approximation method. The obtained J-V
characteristic is compared with previously reported experimental work on
p-type GaSe sample. The comparison shows very good agreement between
theoretical and experimental result, confirming the correctness of the
analysis.
