From starlight to visibility: researchers develop shortwave infrared technology that enables detection of starlight

Benchmarking HGFETs, InGaAs diodes, and other thin film photodetectors. Credit: Peking University Professor Zhang Zhiyong’s team at Peking University has developed a heterojunction-gate field-effect transistor (HGFET) that achieves high sensitivity in shortwave infrared detection, recording a specific detection power of over 1014 Jones at 1300nm, and detecting starlight. became possible. Their work was recently published in the journal Advanced Materials…
