High Breakdown Voltage: Magetsi owonongeka a GaN ndi apamwamba kwambiri kuposa zida wamba za semiconductor, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mphamvu zamagetsi.

Magetsi:
Kachulukidwe Wamphamvu Kwambiri: Zophika za GaN-on-Diamond zimathandizira kutulutsa mphamvu zambiri kwinaku akusunga mawonekedwe ang'onoang'ono, abwino kwa amplifiers ndi makina a RF.
Kutayika Kwapang'onopang'ono: Kuphatikizika kwa mphamvu ya GaN ndi kutentha kwa diamondi kumabweretsa kuchepa kwa mphamvu panthawi yogwira ntchito.

Ubwino wa Pamwamba:
Kukula Kwapamwamba kwa Epitaxial: Wosanjikiza wa GaN amakula mopitilira muyeso pagawo la diamondi, kuwonetsetsa kuti kachulukidwe kakang'ono ka dislocation, mtundu wapamwamba wa crystalline, komanso magwiridwe antchito a chipangizocho.

Kufanana:
Makulidwe ndi Mapangidwe Ofanana: Zosanjikiza zonse za GaN ndi gawo lapansi la diamondi zimasunga zofananira, zofunika kuti chipangizocho chizigwira ntchito komanso kudalirika.

Kukhazikika kwa Chemical:
Onse a GaN ndi diamondi amapereka kukhazikika kwapadera kwamankhwala, kulola kuti zophika izi zizigwira ntchito modalirika m'malo ovuta.

A4:Inde, zowotcha za GaN-on-Diamond ndizoyenera kugwiritsa ntchito malo ndi ndege chifukwa cha kudalirika kwambiri, mphamvu zoyendetsera kutentha, komanso kugwira ntchito m'malo ovuta kwambiri, monga kutentha kwakukulu, kusiyana kwa kutentha, ndi ntchito yothamanga kwambiri.

Q5: Kodi zida zopangidwa kuchokera ku zowotcha za GaN-on-Diamond zimakhala zotani?

A5:Kuphatikiza kwa kulimba kwachilengedwe kwa GaN ndi zida zapadera za diamondi zowononga kutentha kumapangitsa kuti zida zizikhala ndi moyo wautali. Zida za GaN-on-Diamond zidapangidwa kuti zizigwira ntchito m'malo ovuta komanso mphamvu zamphamvu kwambiri zomwe zimawonongeka pang'ono pakapita nthawi.

Q6: Kodi kutentha kwa diamondi kumakhudza bwanji magwiridwe antchito a GaN-on-Diamond wafers?

A6:Kutentha kwapamwamba kwa diamondi kumagwira ntchito yofunika kwambiri popititsa patsogolo magwiridwe antchito a zowotcha za GaN-on-Diamond pochotsa bwino kutentha komwe kumapangidwa mumagetsi apamwamba kwambiri. Izi zimawonetsetsa kuti zida za GaN zimasunga magwiridwe antchito bwino, zimachepetsa kupsinjika kwamafuta, ndikupewa kutenthedwa, zomwe zimakhala zovuta kwambiri pazida zodziwika bwino za semiconductor.

Q7: Ndi ntchito ziti zomwe zowotcha za GaN-on-Diamond zimaposa zida zina za semiconductor?

A7:Zophika za GaN-on-Diamond zimaposa zida zina pamapulogalamu omwe amafunikira kugwiritsa ntchito mphamvu zambiri, kugwiritsa ntchito pafupipafupi, komanso kuwongolera bwino kwamafuta. Izi zikuphatikiza zokulitsa mphamvu za RF, makina a radar, kulumikizana ndi ma microwave, kulumikizana ndi satelayiti, ndi zamagetsi zina zamphamvu kwambiri.

Mapeto

Zophika za GaN-on-Diamond zimapereka yankho lapadera la ntchito zothamanga kwambiri komanso zamphamvu kwambiri, kuphatikiza magwiridwe antchito apamwamba a GaN ndi matenthedwe apadera a diamondi. Ndi mawonekedwe osinthika, amapangidwa kuti akwaniritse zosowa zamafakitale omwe amafunikira mphamvu yoperekera mphamvu, kasamalidwe kamafuta, komanso magwiridwe antchito apamwamba, kuonetsetsa kudalirika komanso moyo wautali m'malo ovuta.
