| Popis: | This work shows the large‐area growth of high‐quality vertically aligned PtSe 2 , and its application to photodetectors based on PtSe 2 ‐GaAs heterojunctions which exhibit a broadband sensitivity to illumination ranging from deep ultraviolet to near‐infrared light, with a peak sensitivity in the region from 650 to 810 nm. The high‐performance broadband photodetector will develop the next‐generation 2D Group‐10 materials based optoelectronic devices. |
