Abstract
The total spontaneous emission rate (R(sp)) is an important quantity, which is widely used in the particle rate equation of light-emitting d iodes and semiconductor lasers. It is important to find the explicit d ependence of R(sp) on electron and hole concentrations. Such an approx imate analytical expression is proposed both for two- and three-dimens ional systems. Accuracy of the approximation is within 15% for undoped and 25% for doped semiconductors. Dependence of the relative error on the electron-hole concentrations and a quantitative comparison of the approximate and exact expressions are illustrated.
