Abstract
Experimental data are presented showing efficiency enhancements due to size reductions of apertured quantum dot microcavity light emitting diodes. The aperture sizes are photolithographically controlled to generate four diffe rent aperture sizes that are nominally 4, 3, 2, and 1 mum diameters. Even a t room temperature the efficiencies increase with decrease in aperture size . (C) 2001 American Institute of Physics.
