Abstract
Improved quantum efficiency of multiple quantum wells. In accordance with an embodiment of the present invention, an article of manufacture includes a p side for supplying holes and an n side for supplying electrons. The article of manufacture also includes a plurality of quantum well periods between the p side and the n side, each of the quantum well periods includes a quantum well layer and a barrier layer, with each of the barrier layers having a barrier height. The plurality of quantum well periods include different barrier heights.
