Imiterere yibikoresho hamwe na karubide ya silicon yacumuye munsi yumuvuduko wikirere

Ibisobanuro by'incamake】 Muri C, N, B hamwe nibindi bikoresho bitarimo okiside yo mu rwego rwo hejuru ibikoresho byibanze byangiza, umuvuduko wikirere wacumuyesilicon karbideni nini kandi yubukungu, kandi birashobora kuvugwa ko ari umusenyi cyangwa emera. Byerasilicon karbideni ibara ritagaragara. Noneho imiterere yibintu nibirangasilicon karbide?

 

Imiterere yibikoresho byumuvuduko wikirere byacumuyesilicon karbide:

Umuvuduko w'ikirere wacumuyesilicon karbideikoreshwa mu nganda ni umuhondo woroshye, icyatsi, ubururu n'umukara ukurikije ubwoko n'ibirimo umwanda, kandi ubuziranenge buratandukanye kandi gukorera mu mucyo biratandukanye. Imiterere ya silicon karbide ya kirisiti igabanijwemo amagambo atandatu cyangwa diyama imeze nka plutonium na cubic plutonium-sic. Plutonium-sic ikora deforme zitandukanye bitewe nuburyo butandukanye bwo gutondekanya atome ya karubone na silicon muburyo bwa kristu, kandi habonetse ubwoko burenga 70 bwo guhindura ibintu. beta-SIC ihinduka alpha-SIC hejuru ya 2100.Inganda zinganda za karubide ya silicon yatunganijwe neza hamwe numusenyi wo mu bwoko bwa quartz wo mu rwego rwo hejuru hamwe na kokiya ya peteroli mu itanura rirwanya. Carbide itunganijwe neza ya silicon irajanjagurwa, isuku-ishingiye kuri aside, gutandukanya magnetiki, gusuzuma cyangwa guhitamo amazi kugirango bitange ibicuruzwa bitandukanye bingana.

 

Ibintu biranga umuvuduko wikirereicyuma cya silicon karbide:

Carbide ya Silicon ifite imiti ihamye, itwara ubushyuhe, coefficente yo kwagura ubushyuhe, kwambara birwanya, bityo usibye gukoresha nabi, hari byinshi byakoreshwa: Urugero, ifu ya karubide ya silikoni yometse kurukuta rwimbere rwumubyimba wa turbine cyangwa silinderi hamwe inzira idasanzwe, irashobora kunoza imyambarire no kwagura ubuzima inshuro 1 kugeza kuri 2. Ikozwe nubushyuhe butarwanya ubushyuhe, ubunini buto, uburemere bworoshye, imbaraga nyinshi zibikoresho byo murwego rwohejuru, imbaraga zingirakamaro nibyiza cyane. Carbide yo mu rwego rwo hasi (harimo 85% SiC) ni deoxidizer nziza yo kongera umuvuduko wo gukora ibyuma no kugenzura byoroshye imiti kugirango yongere ubwiza bwibyuma. Byongeye kandi, umuvuduko wikirere wacumuye silicon karbide nayo ikoreshwa cyane mugukora ibice byamashanyarazi bya karuboni ya karubone.

Carbide ya Silicon irakomeye cyane. Ubukomere bwa Morse ni 9.5, bukurikira kabiri nyuma ya diyama ikomeye ku isi (10), ni umuyoboro wa semiconductor ufite ubushyuhe bwiza cyane, urashobora kurwanya okiside ku bushyuhe bwinshi. Carbide ya Silicon ifite byibura ubwoko 70 bwa kristaline. Carbide ya Plutonium-silicon ni isomer isanzwe ikora ku bushyuhe buri hejuru ya 2000 kandi ifite imiterere ya kristu ya mpandeshatu (isa na wurtzite). Carbide ya silicon yamenetse munsi yumuvuduko wikirere

 

Gushyira mu bikorwasilicon karbidemu nganda ziciriritse

Uruganda rwa silicon karbide semiconductor inganda zirimo cyane cyane silicon karbide ifu yuzuye-isuku, ifu ya kirisiti imwe, urupapuro rwa epitaxial, ibice byamashanyarazi, gupakira module hamwe nibisabwa.

1. Kugeza ubu, uburyo bwo gukura bwa SiC imwe ya kristu harimo uburyo bwo kohereza imyuka yumubiri (uburyo bwa PVT), uburyo bwamazi bwamazi (uburyo bwa LPE), hamwe nubushyuhe bwo hejuru bwoherejwe nubumara (uburyo bwa HTCVD). Carbide ya silicon yamenetse munsi yumuvuduko wikirere

2. Urupapuro rwa Epitaxial Urupapuro rwa epicaxial Silicon, urupapuro rwa karibide ya silicon, firime imwe ya kirisiti (epitaxial layer) ifite icyerekezo kimwe na kristu ya substrate ifite ibisabwa bimwe na bimwe bya karubide ya silicon. Mubikorwa bifatika, ibikoresho bigari bya semiconductor ibikoresho hafi ya byose bikozwe mubice bya epitaxial, kandi chip ya silicon ubwayo ikoreshwa gusa nka substrate, harimo na substrate ya GaN epitaxial layer.

3.

4. Ukurikije uburyo bukoreshwa bwiki gikoresho, ibikoresho bya SiC bitanga amashanyarazi ahanini birimo diode yamashanyarazi hamwe numuyoboro wamashanyarazi.

5. Bitewe nuburyo bwiza bwo guhindura, ibiranga ubushyuhe buke, uburemere nibindi byiza byibikoresho bya SiC, ibyifuzo byinganda zo hasi bikomeje kwiyongera, kandi hariho inzira yo gusimbuza ibikoresho bya SiO2.
