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.

WebAlthough this procedure extracts a 2D Auger coefficient from the QW laser threshold, and all state-of-the-art III-V mid-IR lasers employ T1 or T2 QWs instead of bulk materials, it is... WebHere, we present first-principles-based investigations of Auger recombination processes in InAs. For the direct process, we calculate an Auger coefficient of 1.6 × 10 −27 cm 6 s −1 ; …
WebThe zero-threshold Auger recombination channel in QDs is shown to dominate at low (below 200 K) temperature, whereas at higher temperatures the quasithreshold channel becomes dominant. The effective 3D Auger coefficient is estimated in the approximation of a spherical QD, and a good agreement with the experimental data is obtained. WebIt is discovered that the InAs/InAlAs NWs have a very low Auger rate (ten-fold smaller than planar zincblende InAs) and a high radiative rate, which results in a high estimated 77 K …
