Abstract
We demonstrate an InGaAs nanomembrane field-effect phototransistor with wide-band spectral response tunability, from the visible to near-infrared light. The ultra-thin InGaAs channel (15nm) device, enabled by epitaxial lift-off of InGaAs-on-InP MOSHEMT, is integrated with a fully exposed channel for photosensitivity enhancement. The photocurrent is tunable >5 orders for a gate bias range of 6 V. On-state photo-responsivities of 380 A/W to 15 A/W for 660 nm to 1877 nm light is measured, >2× more sensitive than existing silicon and III-V photodetectors [1]–[3]. The device shows no performance degradation when flexed down to 10-cm radius, showing suitability for conformal surface sensor applications.
