摘要：

Results are presented on planar microcavity light emitting diodes with different device diameters. A record external quantum efficiency of 20% is achieved for a 1.5 mm light emitting diode, The strong dependence of the quantum efficiency on current density and device size are compared with theoretical results, A good correspondence is obtained when spectral broadening and photon recycling are taken into account.
