【Abstract】 A novel optoelectronic functional circuit with heterojunction phototransistors (HPTs) and resonant tunneling diodes (RTDs) is described,which presents the function of both photocurrent switching and photo-current latching.These behaviors have been demonstrated by simulating experiments and circuit simulation.Furthermore,basing on photo-current latching behavior,various photo-controlled basis logic elements such as delayed flip-flop (DFF) can be designed and fabricated.更多还原
