WebMay 23, 2016 · Abstract The potential applications of germanium and its alloys in infrared silicon-based photonics have led to a renewed interest in their optical properties. In this letter, we report on the numerical determination of Auger coefficients at T = 300 K for relaxed and biaxially strained germanium. WebNov 11, 1998 · For energy gaps corresponding to 3.1–4.8 μm, the room-temperature Auger coefficients for seven different samples are found to be nearly an order-of-magnitude lower than typical type-I results for the same wavelength. The data imply that at this … Two different approaches, a photoconductive response technique and a correlatio… We would like to show you a description here but the site won’t allow us.
