A research team led by Professor Zhang Zhiyong at Peking University has developed an innovative short-wave infrared (SWIR) detector with remarkable sensitivity and high photoresponse, capable of detecting starlight. The new detector, based on a heterojunction-gated field-effect transistor (HGFET), achieves a specific detectivity over 10¹⁴ Jones at 1300 nm, establishing a new benchmark in infrared detection.
