In-operando strain mapping of electrically pumped GeSn micro-ring lasers

We propose to employ in-operando Scanning X-ray Diffraction Microscopy (SXDM) to investigate the impact of the heat generated during their operation on the active layer lattice...本研究提出采用原位扫描X射线衍射显微镜（in-operando Scanning X-ray Diffraction Microscopy, SXDM），探究器件运行过程中产生的热量对其活性层晶格的影响……
