Abstract
Embodiments are directed to glass-ceramic substrates with a III-V semiconductor layer, for example, a GaN layer that can be used in LED lighting devices. The glass-ceramics material is in the anorthite-rutile (CaAl2Si2O8+TiO2) family or in the cordierite-enstatite (SiO2—Al2O3—MgO—TiO2) family.
