摘要

建立了基于八波段kp形式和包络函数近似(EFA)形式的理论框架来研究GeSn合金的发光性能。利用该框架，估算了Ge0.83 Sn0.17样品在4-80 K温度范围内的稳态辐射载流子寿命，其数量级为ns。

Radiative Carrier Lifetime in GeSn Mid-Infrared Emitters

A theoretical framework based on the eight-band k.p formalism and the envelope function approximation (EFA) formalism is developed to investigate the luminescence properties of GeSn alloys. Using this framework, the steady-state radiative carrier lifetimes of Ge0.83 Sn0.17 samples are estimated in the ns order over the 4–80 K temperature range.
