Abstract
Solid state lighting devices with semi-polar or non-polar surfaces and associated methods of manufacturing are disclosed herein. In one embodiment, a solid state lighting device includes a substrate material having a substrate surface and an epitaxial silicon structure in direct contact with the substrate surface. The epitaxial silicon structure has a sidewall extending away from the substrate surface. The solid state lighting device also includes a semiconductor material on at least a portion of the sidewall of the epitaxial silicon structure. The semiconductor material has a semiconductor surface that is spaced apart from the substrate surface and is located on a semi-polar or non-polar crystal plane of the semiconductor material.
