"on graphene/AlN templates by MOCVD, surface pits effect in AlN on growth and exfoliation of these thin films... nano-sized pits on AlN surface led to degradation of graphene near them at higher temperatures, altering GaN thin film growth modes to bond with AlN substrat causing film exfoliation failure... structural problems in substrate also cause peeling failure,.. substrate recycling is possible... improves semiconductor industry... Moore's law overcome... EVs, LEDs, photodetectors, and power electronic devices"
