Shockley-read-hall 复合

Web25 May 2016 · Defect-assisted nonradiative Shockley-Read-Hall recombination is an important process in wide-band-gap semiconductors. However, nonradiative capture rates decrease exponentially with the energy of the transition, and therefore the mechanisms by which such recombination can take place are unclear. The authors show here that excited … http://icqd.ustc.edu.cn/2024/0217/c9116a413369/page.htm
