Silicon carbide ibikoresho Nibiranga

Igikoresho cya Semiconductor nicyo kintu cyibikoresho bigezweho byimashini zinganda, zikoreshwa cyane muri mudasobwa, ibikoresho bya elegitoroniki y’abaguzi, itumanaho ry’urusobe, ibikoresho bya elegitoroniki, n’ibindi bice by’ibanze, inganda zikoresha igice kinini zigizwe n’ibice bine by’ibanze: imiyoboro ihuriweho, ibikoresho bya optoelectronic, igikoresho cyihariye, sensor, kibarirwa hejuru ya 80% yumuzunguruko uhuriweho, kenshi na semiconductor hamwe nu muzunguruko uhwanye.

Umuzunguruko wuzuye, ukurikije icyiciro cyibicuruzwa bigabanijwemo ibyiciro bine: microprocessor, kwibuka, ibikoresho bya logique, ibice byigana. Ariko, hamwe no kwaguka kwaguka kwimyanya ikoreshwa ryibikoresho bya semiconductor, ibihe byinshi bidasanzwe bisaba semiconductor kugirango ibashe gukurikiza ikoreshwa ryubushyuhe bwo hejuru, imirasire ikomeye, imbaraga nyinshi nibindi bidukikije, ntibishobora kwangiza, igisekuru cya mbere nicyakabiri ibikoresho bya semiconductor nta mbaraga bifite, nuko igisekuru cya gatatu cyibikoresho bya semiconductor byaje kubaho.

Kugeza ubu, ibikoresho bigari bya semiconductor ibikoresho byerekanwe nasilicon karbide. Igisekuru cya gatatu cyibikoresho bya semiconductor hamwe nubugari bwagutse bwagutse, niko umurima wamashanyarazi usenyuka, ubushyuhe bwumuriro, umuvuduko wuzuye wa elegitoronike hamwe nubushobozi buke bwo kurwanya imirasire, bikwiranye no gukora ubushyuhe bwinshi, inshuro nyinshi, kurwanya imirasire nibikoresho bikoresha ingufu nyinshi , mubisanzwe bizwi nkibikoresho bigari bya semiconductor yagutse (ubugari bwabujijwe kurenza 2.2 eV), byitwa kandi ubushyuhe bwo hejuru ibikoresho bya semiconductor. Duhereye ku bushakashatsi buriho ku bikoresho bya semiconductor yo mu gisekuru cya gatatu, ibikoresho bya silicon karbide na gallium nitride ibikoresho bya semiconductor birakuze, kandisilicon carbide tekinorojini ikuze cyane, mugihe ubushakashatsi kuri zinc oxyde, diyama, nitride ya aluminium nibindi bikoresho biracyari mubyiciro byambere.

Ibikoresho n'imiterere yabyo :

Carbideibikoresho bikoreshwa cyane mubitereko byumupira wumubumbyi, indangagaciro, ibikoresho bya semiconductor, giros, ibikoresho byo gupima, ikirere nizindi nzego, byahindutse ibikoresho bidasubirwaho mubikorwa byinshi byinganda.

SiC ni ubwoko bwa superlattice karemano hamwe na polytype isanzwe. Hariho imiryango irenga 200 (kuri ubu izwi) homotypic polytypic imiryango bitewe nuburyo butandukanye bwo gupakira ibintu hagati ya diatomic ya Si na C, biganisha kubintu bitandukanye bya kristu. Kubwibyo, SiC irakwiriye cyane kubisekuru bishya byumucyo utanga diode (LED) ibikoresho byububiko, ibikoresho bya elegitoroniki bikomeye.

umutungo kamere

Gukomera cyane (3000kg / mm), birashobora guca rubini
Kurwanya kwambara cyane, kumwanya wa kabiri nyuma ya diyama
Amashanyarazi yumuriro arenze inshuro 3 kurenza Si na 8 ~ 10 hejuru ya GaAs.
Ubushyuhe bwumuriro wa SiC buri hejuru kandi ntibishoboka gushonga kumuvuduko wikirere
Imikorere myiza yo gukwirakwiza ubushyuhe ningirakamaro cyane kubikoresho bifite ingufu nyinshi
 

 

umutungo wa shimi

Kurwanya ruswa cyane, irwanya hafi ikintu cyose kizwi cyangirika mubushyuhe bwicyumba
Ubuso bwa SiC bworoshye okiside kugirango ikore SiO, igicucu cyoroshye, irashobora gukumira okiside yayo, muri Hejuru ya 1700 ℃, firime ya oxyde irashonga kandi igahinduka vuba
Umuyoboro wa 4H-SIC na 6H-SIC wikubye inshuro 3 uwa Si na inshuro 2 za GaAs: Kumeneka amashanyarazi yamashanyarazi ni gahunda yubunini burenze Si, kandi umuvuduko wa electron umuvuduko wuzuye Inshuro ebyiri nigice Si. Igipande cya 4H-SIC ni kinini kuruta icya 6H-SIC
