WebThe Trap-Assisted Recombination model is used for setting the electron and hole recombination rates in indirect-band-gap semiconductors. By default, steady-state recombination is modeled using the Shockley–Read–Hall … WebThe effect of such recombination centres can be adequately described with the Shockley-Read-Hall model (Hall, 1952; Shockley and Read, 1952). For the common case that the … In Shockley-Read-Hall recombination ( SRH ), also called trap-assisted recombination, the electron in transition between bands passes through a new energy state (localized state) created within the band gap by a dopant or a defect in the crystal lattice; such energy states are called traps.

WebThe physical section of the simulation included a doping dependence mobility model together with Shockley-Read-Hall and Auger recombination processes as was considered in a paper [15]. In the actual context, it is assumed that the electrical ohmic contacts are ideal and the contact regions could support a sufficiently high dopant concentration.
