Nyeredzi iri kubuda yechizvarwa chechitatu semiconductor: Gallium nitride akati wandei mapoinzi ekukura mune ramangwana

Zvichienzaniswa nesilicon carbide madivayiri, gallium nitride magetsi maturusi achave nezvakawanda zvakanakira mumamiriro ezvinhu apo kushanda zvakanaka, kuwanda, vhoriyamu uye zvimwe zvakazara zvinhu zvinodiwa panguva imwe chete, senge gallium nitride based zvishandiso zvakashandiswa zvinobudirira mumunda wekukurumidza kuchaja pa. chikero chikuru. Nekubuda kwezvishandiso zvitsva zvekudzika pasi, uye nekuenderera mberi kwegallium nitride substrate kugadzirira tekinoroji, GaN zvishandiso zvinotarisirwa kuramba zvichiwedzera huwandu, uye ichave imwe yeakakosha matekinoroji ekudzikisa mutengo uye kushanda zvakanaka, kusimudzira girinhi kusimukira.

Parizvino, chizvarwa chechitatu che semiconductor zvinhu chave chikamu chakakosha chehurongwa hwemaindasitiri ari kusimukira, uye zvakare iri kuve iyo nzira yekuraira kutora chizvarwa chinotevera cheruzivo tekinoroji, kuchengetedza simba uye kuderedzwa kwekubuda uye tekinoroji yekuchengetedza nyika. Pakati pavo, gallium nitride (GaN) ndeimwe yeanomiririra yechitatu-chizvarwa semiconductor zvinhu seyakafara bandgap semiconductor zvinhu zvine bandgap ye3.4eV.

Musi waChikunguru 3, China yakasimbisa kutengeswa kunze kwenyika kwegallium uye germanium zvinhu zvine hukama, inova yakakosha kugadziridzwa kwebumbiro kunoenderana neakakosha hunhu hwegallium, isingawanzo simbi, se "zviyo zvitsva zveindasitiri yesemiconductor," uye yakanakira kushandiswa kwayo mukati. semiconductor zvinhu, simba idzva uye mamwe minda. Tichifunga nezvekuchinja kwemitemo iyi, pepa rino richakurukura nekuongorora gallium nitride kubva kune zvekugadzirira tekinoroji nematambudziko, mapoinzi matsva ekukura mune ramangwana, uye maitiro emakwikwi.

Sumo pfupi:
Gallium nitride imhando yekugadzira semiconductor zvinhu, inova yakajairwa mumiriri wechizvarwa chechitatu che semiconductor zvinhu. Kana ichienzaniswa neyechinyakare silicon zvinhu, gallium nitride (GaN) ine zvakanakira bhendi-gap hombe, yakasimba breakdown yemagetsi munda, yakaderera pa-resistance, high electron mobility, yakakwirira kutendeuka kushanda zvakanaka, yakakwirira yekupisa conductivity uye kurasikirwa kwakaderera.

Gallium nitride single crystal chizvarwa chitsva che semiconductor zvinhu zvine mashandiro akanakisa, ayo anogona kushandiswa zvakanyanya mukutaurirana, radar, zvemagetsi zvevatengi, mota dzemagetsi, simba remagetsi, indasitiri laser processing, instrumentation uye mamwe minda, saka kusimudzira kwayo uye kugadzirwa kwakawanda ndiko. kutarisa kwekutarisisa kwenyika nemaindasitiri pasi rese.

Kushandiswa kweGaN

1--5G yekutaurirana base chiteshi
Wireless kutaurirana zvivakwa ndiyo huru yekushandisa nzvimbo ye gallium nitride RF zvishandiso, inoverengera makumi mashanu%.
2--Magetsi epamusoro
Iyo "double height" yeGaN ine mukana wakakura wekupinda mumidziyo yemagetsi yevatengi, inogona kusangana nezvinodiwa zvekuchaja nekukurumidza uye mamiriro ekudzivirira.
3--Motokari itsva ine simba
Kubva pamaonero anoshanda ekushandisa, ikozvino yechitatu-chizvarwa semiconductor zvishandiso pamotokari zvinonyanya silicon carbide zvishandiso, asi kune akakodzera gallium nitride zvinhu zvinogona kupfuudza mota yemutemo chitupa chemagetsi mudziyo modules, kana dzimwe dzakakodzera nzira dzekurongedza, dzichaita. zvichiri kugamuchirwa nechirimwa chose uye vagadziri veOEM.
4--Data centre
GaN magetsi semiconductors anonyanya kushandiswa muPSU magetsi ekupa zvikamu munzvimbo dzedata.

Muchidimbu, nekubuda kwezvishandiso zvitsva zvakaderera uye kuenderera mberi kwegallium nitride substrate kugadzirira tekinoroji, GaN zvishandiso zvinotarisirwa kuramba zvichiwedzera huwandu, uye ichave imwe yeakakosha matekinoroji ekudzikisa mutengo uye kushanda nesimba uye inoenderera girinhi budiriro.
