Method for manufacturing a semiconductor micro- or nano-wire, semiconductor structure comprising such a micro- or nano-wire, and method for manufacturing a semiconductor structure

摘要

A method of manufacturing at least one semiconducting micro- or nano-wire used for formation of an optoelectric structure, optoelectronic structures including the micro- or nano-wires, and a method enabling manufacture of the photoelectronic structures. The method includes providing a semiconducting substrate, forming a crystalline buffer layer on the substrate, the buffer layer having a first zone over at least part of its thickness composed mainly of magnesium nitride in a form Mg_xN_y, and forming at least one semiconducting micro- or nano-wire on the buffer layer.
