NANOWIRES-BASED LIGHT EMITTERS ON THERMALLY AND ELECTRICALLY CONDUCTIVE SUBSTRATES AND OF MAKING SAME

摘要

Elemental or compound semiconductors on metal substrates and methods of growing them are provided. The methods can include the steps of: (i) providing a metal substrate; (ii) adding an interlayer on a surface of the metal substrate, and (iii) growing semiconductor nanowires on the interlayer using a semiconductor epitaxy growth system to form the elemental or compound semiconductor. The method can include direct growth of high quality group III-V and group III-N based materials in the form of nanowires and nanowires-based devices on metal substrates. The nanowires on all-metal scheme greatly simplifies the fabrication process of nanowires based high power light emitters.
