GaAs/InGaP and AlGaAs/GaAs/InAlGaP npn heterostructural optoelectronic switches (HSOSs) have been fabricated to demonstrate the bulk-barrier and potential-spike height effects on the switching. It is seen that the illumination decreases the switching voltage VS and increases the switching current IS in the GaAs/InGaP HSOS characteristics. But in the AlGaAs/GaAs/InAlGaP HSOS, the VS and IS present contrary trends. These characteristic variation differences in the two HSOSs are mainly due to the photogenerated carriers that affect the bulk-barrier and potential-spike heights.
