Shockley-read-hall process
http://meroli.web.cern.ch/Lecture_lifetime.html WebShockley-Read-Hall (SRH) recombination is the dominant recombination mechanism at lower carrier concentrations. First-principles calculations of the SRH recombination rate were pioneered in the Van de Walle group at the University of California, Santa Barbara by Prof. Audrius Alisauskas [ Alkauskas et al., 2014] .

WebTrap-Assisted Recombination. This feature is an expanded version of the original Shockley-Read-Hall Recombination feature, with new options to allow for more detailed modeling of traps. Use the Trap-Assisted Recombination model to set the electron and hole recombination rates in indirect band-gap semiconductors such as silicon under low ... WebIn the bulk of the material the carriers recombine by either radiative (also known as band-to-band) recombination, Auger recombination or Shockley-Read-Hall (SRH) via traps within the energy gap. The lifetime of carriers in the material bulk τ b is composed of radiative lifetime τ rad , Auger lifetime τ A and a SRH lifetime τ SRH with the relation:
Web5 Jun 2014 · CMOS image sensor: Process impact on dark current Abstract: Dark current is a major concern for the CMOS Image sensor. If the Shockley-Read-Hall generation creates this current, the origin of defects is multiple. Metallic contaminants cause deep level bulk defects, this gives the blemish pixels.

WebTrap-Assisted (Shockley-Read-Hall) Recombination. The recombination process in the trap-assisted model assumes that there are unoccupied "trap" states (also referred to deep-level defect states) within the band gap. Typically, these states result from impurities (either intentional or unintentional), and the most active have energy levels near ... WebShockley-Read-Hall recombination can be considered as the independent capture of electrons and holes by a crystal defect or impurity via interactions with lattice vibrations. Auger recombination is a three-carrier process that involves an electron and a hole recombining across the band gap with the excess energy of that recombination going to a …
WebSince the pioneering work of Shockley, Read, and Hall 1 on the statistics of the recombination of electrons and holes many papers have been published aiming at the im provement of theoretical understanding of these processes, which play an outstanding role in semiconductor devices.
