The theoretical simulations related to the utmost performance of the (100) HgCdTe Auger suppressed structures are presented. Dark current is reported to be reduced by more than one order of magnitude within the range ~6 × 10 ...

http://pv.cecs.anu.edu.au/files/dan2003SRH.pdf 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. Non-radiative … See more In the solid-state physics of semiconductors, carrier generation and carrier recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated. Carrier generation … See more Like other solids, semiconductor materials have an electronic band structure determined by the crystal properties of the material. Energy … See more When light interacts with a material, it can either be absorbed (generating a pair of free carriers or an exciton) or it can stimulate a recombination event. The generated photon has similar properties to the one responsible for the event. Absorption is the … See more Band-to-band radiative recombination Band-to-band recombination is the name for the process of electrons jumping down from the conduction band to the valence band in a radiative … See more Recombination and generation are always happening in semiconductors, both optically and thermally. As predicted by thermodynamics, a material at thermal equilibrium will … See more Carrier recombination can happen through multiple relaxation channels. The main ones are band-to-band recombination, Shockley–Read–Hall (SRH) trap-assisted recombination, Auger recombination and surface recombination. These decay channels can be … See more Non-radiative recombination is a process in phosphors and semiconductors, whereby charge carriers recombine releasing phonons instead … See more WebWe show that in the presence of traps, electron capture rate prescribed by the Shockley–Read–Hall (SRH) formalism is greatly enhanced due to the high electric field … milford primary school nottingham
