We report the growth of direct bandgap single-crystalline Ge 1-x Sn x thin films on unheated substrates by a modified magnetron sputtering system. The Ge 1-x Sn x thin films were deposited on Si, G…
Midwave infrared (3-5 μm) photodetector with high detecting performance at room temperature has always been pursued for wide applications such as remote sensing, medical diagnosis, communication, …
We report high quality GeSn/GaAs heterostructure photodetectors grown by a modified magnetron sputtering system. A metal-semiconductor-metal photoconductor is fabricated to examine the ability of p…
