WebThus the Auger coefficient in the alloy decreases with decreasing temperature, whereas that in the quantum well increases by nearly a factor of 5 between 300 and 77 K. The intensity-dependent photoconductive response to 2.06 μm excitation has been used to determine Shockley-Read and Auger lifetimes for InAs, InAs 0.91 Sb 0.09 , and an InAs 0. ... 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 ; …
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. 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...
WebIn addition, it has a good crystalline quality, strong optical absorption, high quantum efficiency (≈80%), and high operating temperature (HOT).[5] HOT devices normally operate above 77 K which is the main requirement for high-performance IR detectors without the need for cryogenic cooling. WebWhen comparing to 1.5 µm, the Auger coefficient increases approximately two orders of magnitude (100×) as the wavelength is doubled (by use of InAs QWs). If all else is held …
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.
WebDec 31, 1995 · The coefficients for Auger recombination in InSb at room temperature were found to be 1.1{+-}0.5x10{sup -26} cm{sup 6}s{sup -1} and 4.0{+-}0.5x 10{sup -9} cm{sup 3}s{sup -1} in these two regimes. These experiments also reveal associated coherent transient grating effects for the first time in these systems. chip win 21WebNov 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.
