摘要：
The effective charge carrier lifetime in n-type CdHgTe variable-gap structures is calculated with allowance for Auger recombination and recombination at dislocations. It is shown that introducing wide, variable-gap layers can eliminate the effect of surface recombination and yield long effective lifetimes, even for high densities of dislocations (above 10(7) cm(-2)). The calculated charge carrier lifetimes are in agreement with measurements on variable-gap structures grown by molecular-beam epitaxy. (C) 1999 American Institute of Physics. [S1063-7826(99)00803-0].
