Sic sapphire
Webmaterial is the substrate. Four substrates are mentioned, GaN itself, SiC, Sapphire and silicon. Of course, the ideal substrate would be GaN itself, bulk GaN, since GaN shows significant properties superior to other materials. Bulk GaN allows for homo-epitaxy without any mismatches between substrate and WebThese works have demonstrated the first growths of hexagonal and cubic SiC on sapphire and 6H-SiC or silicon, respectively. However, few details have been given concerning the AlN microstructure and the possible interplay between the materials, except for the presence of Al autodoping in SiC during the growth process [ 10 ].
