摘要：
An array of pyramids containing templated InGaN/GaN quantum wells have been fabricated using selective overgrowth above patterned silica masks and studied using cathodoluminescence hyperspectral imaging. The cathodoluminescence reveals bright luminescence at the peaks of the micropyramids, red shifted from that due to similar, conventionally grown planar quantum wells. The possibility that this emission is due to quantum dots is discussed.
