Silicon carbide semiconductor zvinhu

Silicon carbide (SiC)Zvinhu zve semiconductor ndizvo zvakura kupfuura zvimwe zvese zvakagadzirwa ne semiconductors dzakakura. Zvinhu zve semiconductor zve SiC zvine mukana mukuru wekushandiswa mumidziyo inodzivirira kupisa kwakanyanya, ma frequency akawanda, simba guru, photoelectronics uye radiation nekuda kwe wide band gap yavo, high breakdown electric field, high thermal conductivity, high saturation electron movement uye saizi diki. Silicon carbide ine mashandisirwo akasiyana-siyana: nekuda kwe wide band gap yayo, inogona kushandiswa kugadzira ma blue light-emitting diodes kana ultraviolet detectors asinganyanyi kukanganiswa nezuva; Nekuti voltage kana electric field inogona kushivirira kasere pane silicon kana gallium arsenide, inonyanya kukodzera kugadzira michina ine high-voltage high-power yakadai se high-voltage diodes, power triode, silicon controlled uye high-power microwave devices; Nekuda kwekumhanya kwakanyanya kwe saturation electron migration, inogona kugadzirwa kuita mhando dzakasiyana dzemidziyo ine high frequency (RF ne microwave);Silicon carbideinokonzeresa kupisa zvakanaka uye inokonzeresa kupisa zviri nani kupfuura chero chimwe chinhu che semiconductor, izvo zvinoita kuti simbi dzesilicon carbide dzishande pakupisa kwakanyanya.

Semuenzaniso chaiwo, APEI parizvino iri kugadzirira kugadzira sisitimu yayo yekutyaira mota yeDC yeNASA's Venus Explorer (VISE) ichishandisa zvikamu zvesilicon carbide. Chinangwa chayo chiri muchikamu chekugadzira, ndechekuisa marobhoti ekuongorora pamusoro peVenus.

Pamusoro pezvo, skabhidhidhi yealikoniine chisungo chakasimba che ionic covalent, ine kuomarara kwakanyanya, kupisa kunoyerera pamusoro pemhangura, kushanda zvakanaka kwekupisa, kuramba ngura kwakasimba kwazvo, kuramba mwaranzi, kuramba kupisa kwakanyanya uye kugadzikana kwemakemikari zvakanaka nezvimwe zvinhu, ine mashandisirwo akasiyana-siyana mumunda wetekinoroji yemuchadenga. Semuenzaniso, kushandiswa kwezvinhu zvesilicon carbide kugadzirira spacecraft kuti vafambi vemuchadenga, vaongorori vagare uye vashande.
