Abstract

We propose a phototransistor geometry that incorporates silicon nanowires (SiNW) in the device channel. A set of two gates controls the charge flow inside the NW. This improves the device photo-response more than 10x when compared with a single gate phototransistor, leading to a photo-responsivity of greater than 104(A/W), while the dark properties of both devices are similar.
