Electronic device with a wire element extending from an electroconductive layer comprising zirconium carbide or hafnium carbide

摘要

The electronic device comprises a substrate (1), at least one semiconductor wire element (2) formed by a nitride of a group III material and an electroconductive layer (3) interposed between the substrate (1) and said at least one semiconductor wire element (2). Said at least one semiconductor wire element (2) extends from said electroconductive layer (3), and the electroconductive layer (3) comprises a carbide of zirconium or a carbide of hafnium.
