Semicera e motlotlo ho hlahisaGa2O3Substrate, thepa e tsoetseng pele e malala-a-laotsoe ho fetola matla a elektronike le optoelectronics.Gallium oxide (Ga2O3) li-substrateli tsebahala ka li-bandgap tsa tsona tse pharalletseng haholo, e leng se etsang hore e be tse loketseng lisebelisoa tsa matla a holimo le a maqhubu a holimo.
Likarolo tsa Bohlokoa:
• Ultra-Wide Bandgap: Ga2O3 e fana ka bandgap e ka bang 4.8 eV, e matlafatsang haholo bokhoni ba eona ba ho sebetsana le maemo a phahameng le mocheso ha o bapisoa le lisebelisoa tsa setso tse kang Silicon le GaN.
• High Breakdown Voltage: Ka sebaka se ikhethang sa ho senyeha, theGa2O3Substratee nepahetse bakeng sa lisebelisoa tse hlokang ts'ebetso ea motlakase o phahameng, e netefatsang ts'ebetso e kholo le ho ts'epahala.
• Thermal Stability: Thepa e phahameng ea mocheso e tsitsitseng e etsa hore e tšoanelehe bakeng sa likopo maemong a feteletseng, ho boloka ts'ebetso esita le tlas'a maemo a thata.
• Lisebelisoa tse Fetohang: E loketse ho sebelisoa ho li-transistors tsa matla a phahameng, lisebelisoa tsa UV optoelectronic, le tse ling, ho fana ka motheo o tiileng oa lisebelisoa tse tsoetseng pele tsa elektroniki.
Eba le bokamoso ba theknoloji ea semiconductor ka Semicera'sGa2O3Substrate. E etselitsoe ho khahlametsa litlhoko tse ntseng li hola tsa lisebelisoa tsa elektroniki tsa matla a holimo le a maqhubu a holimo, substrate ena e beha maemo a macha a ts'ebetso le ho tšoarella. Tšepa Semicera ho fana ka litharollo tse ncha bakeng sa lits'ebetso tsa hau tse thata ka ho fetisisa.
