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

Zvichienzaniswa nesilicon carbide madivayiri, gallium nitride magetsi emagetsi achave neakawanda mabhenefiti mumamiriro ezvinhu apo kushanda zvakanaka, kuwanda, huwandu uye mamwe maficha akazara anodiwa panguva imwe chete, senge gallium nitride yakavakirwa michina yakave yakabudirira kushandiswa mumunda wekukurumidza kuchaja pamwero mukuru. 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 kutengesa kunze kwegallium uye germanium zvinhu zvine hukama, inova yakakosha bumbiro remitemo yakavakirwa paunhu hunokosha hwegallium, simbi isingawanzo, se "zviyo zvitsva zveindasitiri semiconductor," uye zvakanakira kushandiswa kwayo mu 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 akanaka, anogona kushandiswa zvakanyanya mukutaurirana, radar, zvemagetsi zvevatengi, zvemagetsi zvemotokari, simba remagetsi, indasitiri laser processing, instrumentation uye mamwe minda, saka kusimudzira kwayo uye kugadzirwa kwakawanda ndiko kutariswa 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 pakuona kwekushandisa kwekuona, ikozvino yechitatu-chizvarwa semiconductor zvishandiso pamotokari zvinonyanya kushandiswa nesilicon carbide, asi pane zvakakodzera gallium nitride zvinhu zvinogona kupasa motokari yemitemo yemagetsi emagetsi emagetsi, kana dzimwe nzira dzakakodzera dzekurongedza, dzicharamba dzichigamuchirwa 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.
