WebNov 17, 2015 · I have been doing some research into PN junction diodes and understand that you have one junction which is formed by a p-type region and an n-type region. These two regions have been doped with impurities to give an excess of electrons (free electrons) in the n-type region and a deficit of electrons (free holes) in the p-type region. Webpn = ni2, where ni is the free carrier density in the bulk Silicon at the ambient temperature. The basic recombination process is band-to-band recombination where an electron-hole …

http://web.mit.edu/6.012/www/SP07-L14.pdf WebThe minority carrier lifetime of a material, denoted by τ n or τ p, is the average time which a carrier can spend in an excited state after electron-hole generation before it recombines. It is often just referred to as the "lifetime" and has nothing to do with the stability of the material. Stating that "a silicon wafer has a long lifetime ...
