摘要
How is the efficiency of Auger recombination in PbSnTe structures influenced by the reduction of dimensionality? Two points are investigated, the variation of matrix elements and of activation energies, respectively. It is shown that the latter one gives the more decisive effect. This effect is strongly anisotropic. Thus, {100}-planes or [100]-directions are favoured to yield large Auger lifetimes for Q2D or Q1D structures, respectively.
