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…
The size effect on the electronic structure and optical properties of cubic CsPbBr 3 perovskite quantum dots is investigated by using an 8-band k·p model based on effective-mass envelope function …
We extend the previous 30-band k . p model effectively employed for relaxed Ge 1-x Sn x alloy to the case of strained Ge 1-x Sn x alloy. The strain-relevant parameters for the 30-band k . p model a…
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…
