Abstract
A device includes a substrate; a group III-V semiconductor layer disposed over the substrate; and a seed layer disposed over the group III-V semiconductor layer. The substrate is a printed circuit board. The group III-V semiconductor layer includes a multiple quantum well (MQW) layer, a p-type doped layer, and an n-type doped layer. The seed layer includes a plurality of miniature elements. The miniature elements each contain a single-crystal material suitable for epitaxially growing the group III-V semiconductor layer. The miniature elements collectively cover less than 100% of a surface of the group III-V semiconductor layer.
