使集成光电器件实现常关状态， Kangkai，表明采用该设计方案监测微弱紫外光具有显著优势， we have made ultraviolet (UV) light visible by proposing and fabricating an integrated optoelectronic device. The demonstrated device consists of a GaN-based blue mini-light-emitting diode (mini-LED) and a phototransistor. The phototransistor is specially designed with an Al0.20Ga0.80N polarization gate. The background electrons can be depleted by the polarization gate to enable the normally-off state for the integrated optoelectronic device when there is no UV illumination. Our measured results show that when the polarization-gated phototransistor is switched off， Tian，广东工业大学张紫辉团队报道了通过激发极化栅光电晶体管使紫外光可见，实现了紫外光的可视化， indicating the advantage of monitoring weak UV light by using the proposed design.
