Semiceraka boikakaso e hlahisa sekgala sa yonaEpitaxy ea GaNlits'ebeletso, tse etselitsoeng ho fihlela litlhoko tse lulang li fetoha tsa indasteri ea semiconductor. Gallium nitride (GaN) ke thepa e tsebahalang ka thepa ea eona e ikhethang, 'me lits'ebetso tsa rona tsa kholo ea epitaxial li netefatsa hore melemo ena e fumaneha ka botlalo lisebelisoa tsa hau.
Li-Layers tsa GaN tsa Ts'ebetso e Phahameng Semicerae ikhethang ka tlhahiso ea boleng bo holimoEpitaxy ea GaNmeaho, e fanang ka bohloeki ba lintho tse bonahalang bo ke keng ba lekanngoa le bokhabane ba sebopeho. Likarolo tsena li bohlokoa bakeng sa lits'ebetso tse fapaneng, ho tloha ho matla a elektroniki ho ea ho optoelectronics, moo ts'ebetso e phahameng le ts'epo e hlokahalang. Mekhoa ea rona ea ho hola e nepahetseng e netefatsa hore sekhahla se seng le se seng sa GaN se kopana le litekanyetso tse hlokahalang bakeng sa lisebelisoa tse tsoetseng pele.
Optimized for SebetsaTheEpitaxy ea GaNe fanoeng ke Semicera e etselitsoe ho ntlafatsa ts'ebetso ea likarolo tsa hau tsa elektroniki. Ka ho fana ka likarolo tsa GaN tse nang le sekoli se tlase, tse hloekileng haholo, re nolofalletsa lisebelisoa ho sebetsa ka maqhubu a phahameng le li-voltage, ka tahlehelo ea matla e fokotsehileng. Ntlafatso ena ke senotlolo bakeng sa lits'ebetso tse kang li-high-electron-mobility transistors (HEMTs) le light-emitting diodes (LED), moo ho sebetsa hantle ho leng bohlokoa haholo.
