GeSn alloys fabricated by modified sputtering deposition
Published 2020“…In this thesis, theoretical studies of bulk Ge1-xSnx and Ge1-xSnx/Ge quantum well were carried out by using the 8-band k.p method. The influences of growth condition and characterization environment were investigated, and the calculated parameters, such as spontaneous emission rate of the quantum well provide a good guide for the following experimental work on realizing direct band-gap GexSn1-x thin films. …”
