Epitaxy ea GaN

Tlhaloso e Khutšoanyane:

GaN Epitaxy ke lejoe la sekhutlo tlhahisong ea lisebelisoa tse sebetsang hantle tsa semiconductor, tse fanang ka katleho e ikhethang, botsitso ba mocheso le ho ts'epahala. Litharollo tsa Semicera's GaN Epitaxy li etselitsoe ho fihlela litlhoko tsa lits'ebetso tse tsoetseng pele, ho netefatsa boleng bo holimo le ho tsitsana karolong e ngoe le e ngoe.
