Izinto ze-semiconductor ze-silicon carbide

I-silicon carbide (i-SiC)Izinto ze-semiconductor zezona zivuthiweyo phakathi kwee-semiconductors ze-wide band gap eziphuhlisiweyo. Izinto ze-semiconductor ze-SiC zinamandla amakhulu okusetyenziswa kwizixhobo ezishushu kakhulu, ezihlala ixesha elide, ezinamandla aphezulu, ezisebenzisa i-photoelectronics kunye nezixhobo ezichasene nemitha ngenxa ye-wide band gap yazo, intsimi yombane eqhekekileyo kakhulu, ukuqhuba okuphezulu kobushushu, ukuhamba kwe-electron egcwala kakhulu kunye nobukhulu obuncinci. I-silicon carbide ineendlela ezahlukeneyo zokusetyenziswa: ngenxa ye-wide band gap yayo, ingasetyenziselwa ukwenza ii-diode ezikhupha ukukhanya okuluhlaza okwesibhakabhaka okanye ii-ultraviolet detectors ezingachaphazeleki kakhulu kukukhanya kwelanga; Ngenxa yokuba intsimi yombane okanye yombane inokunyamezelwa izihlandlo ezisibhozo kune-silicon okanye i-gallium arsenide, efanelekileyo ngakumbi ekuveliseni izixhobo zamandla aphezulu ezisebenzisa i-high-voltage ezifana nee-diode ze-high-voltage, i-power triode, izixhobo ze-microwave ezilawulwa yi-silicon kunye nezixhobo ze-high-power microwave; Ngenxa yesantya sokufuduka kwe-electron egcwala kakhulu, ingenziwa ibe zizixhobo ezahlukeneyo ezisebenzisa i-high frequency (RF kunye ne-microwave);I-silicon carbideyi-conductor elungileyo yobushushu kwaye iqhuba ubushushu ngcono kunayo nayiphi na enye into ye-semiconductor, nto leyo eyenza izixhobo ze-silicon carbide zisebenze kumaqondo obushushu aphezulu.

Njengomzekelo othile, i-APEI okwangoku ilungiselela ukuphuhlisa inkqubo yayo yokuqhuba imoto ye-DC engqongileyo kwiVenus Explorer (VISE) ye-NASA isebenzisa izinto ze-silicon carbide. Isekwisigaba soyilo, injongo kukubeka iirobhothi zokuhlola phezu komphezulu weVenus.

Ukongeza, si-ilicon carbideine-ionic covalent bond enamandla, inobunzima obuphezulu, i-thermal conductivity ngaphezu kobhedu, ukusebenza kakuhle kokusasaza ubushushu, ukumelana nokugqwala kunamandla kakhulu, ukumelana nemisebe, ukumelana nobushushu obuphezulu kunye nokuzinza okuhle kweekhemikhali kunye nezinye iimpawu, ineendlela ezahlukeneyo zokusetyenziswa kwicandelo lobuchwepheshe beenqwelo-moya. Umzekelo, ukusetyenziswa kwezinto ze-silicon carbide ukulungiselela i-spacecraft ukuze ii-astronauts, abaphandi bahlale kwaye basebenze.
