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.
