摘要：
The non-stationary thermoelectric model of the axisymmetric heterostructure of a light-emitting device is considered taking into account positive feedback mechanisms and the effect of the current-spreading-layer resistance. Taking into account the current localization effect, the nonuniform distribution of the heterojunction current density over the heterostructure area is determined. The non-stationary thermal conductivity equation with temperature-dependent current density flowing into the heterojunction is solved by the numerical-analytical iterative method. Based on the developed model, the current density, temperature, and thermomechanical stress distributions for the heterojunction plane are determined.
