A physical model with three levels system for stimulated emission, including the Ge NW states for pumping level, the GeSn alloy states, and GeSn core–shell states for stimulation emission level.
Scientists show via first-principles calculations that #TensileStrain and Sn doping induce a direct #bandgap in #GeSn #nanowires, with diameter-dependent symmetry effects enabling >20% EQE near 0.8 eV for #OpticalCommunication.
