A Proposal of a Hetero Junction Bipolar Phototransistor
Ravi Kumar Chanana · Applied sciences research periodicals. · 2025
A hetero junction bipolar phototransistor is proposed in this short communication by adding a second n-Si junction in reverse bias to the already proposed photodiodes on intrinsic semiconductor materials. The transistor having the nano-GaAs emitter can function in the visible range of the electromagnetic spectrum.
