Abstract
In a light-emitting double-heterojunction structure, interface recombination reduces the quantum efficiency of spontaneous emission
; more specifically, in a double-heterojunction laser this increases the threshold current density Jth . Simplified expressions are derived here for the dependence of
and Jth on interface recombination velocities in the injection regimes of both
(or
) and
. Easy-to-handle criteria are presented for checking the validity of the simplifications when using these expressions for evaluating the recombination velocities from experimental data.
