In situ inward epitaxial growth of bulk macroporous single crystals
Abstract
Porous single crystals are desirable for optoelectronic applications, but their fabrication remains challenging. Here the authors produce centimetre-sized macroporous GaN single crystals with electron mobility comparable to that of bulk crystals via in situ inward epitaxial growth on parent LiGaO2 crystals.
