Claim:
1. An optoelectronic light emission device comprising: a gain region of at least one type semiconductor layer that is present in direct contact with a type IV semiconductor substrate, wherein the gain region of the type semiconductor layer has a nanoscale area with a width of 200 nm or less and a length of 200 nm or less, wherein the gain region is present in a pedestal having a height or 1 micron or less, the dimensions of the gain region providing that there are no defects present in the entirety of the gain region, the at least one type semiconductor layer including an epitaxially grown layer having two thicknesses, a first thickness portion measured from an upper surface of the semiconductor substrate that provides the gain region, and a second thickness portion covering a remainder of the semiconductor substrate having a lesser thickness than the first thickness portion.
