Si-based Germanium-Tin (GeSn) Emitters for Short-Wave Infrared Optoelectronics
… single quantum well (QW) and Ge/Ge0.92Sn0.08/Ge double heterostructures (DHS) were studied. The GeSn QW PL emission was scrutinized from 10 to 300 K and the carrier confinement was analyzed through band offset calculations in the QW structure. Moreover, the electrical and optical characteristics …
