Izinto ze-silicon carbide semiconductor

I-silicon carbide (SiC)imathiriyeli ye-semiconductor yeyona ikhulileyo phakathi kwebhendi ebanzi ye-semiconductors ephuhlisiwe. Izixhobo ze-SiC semiconductor zinamandla amakhulu okusebenza kubushushu obuphezulu, ukuphindaphinda okuphezulu, amandla aphezulu, i-photoelectronics kunye nezixhobo ezichasene nemitha ngenxa yesithuba sebhendi ebanzi, intsimi yombane eyophukayo, i-thermal conductivity ephezulu, ukuhamba kwe-electron ephezulu kunye nobukhulu obuncinci. I-Silicon carbide inoluhlu olubanzi lwezicelo: ngenxa ye-gap yayo ebanzi, ingasetyenziselwa ukwenza i-blue light-emitting diode okanye i-ultraviolet detectors enokuthi ichaphazeleke ngokungaqhelekanga kukukhanya kwelanga; Ngenxa yokuba i-voltage okanye intsimi yombane inokunyamezela amaxesha asibhozo kune-silicon okanye i-gallium arsenide, ilungele ngokukodwa ukuvelisa izixhobo eziphezulu ze-high-voltage ezifana ne-high-voltage diode, i-triode yamandla, i-silicon elawulwayo kunye nezixhobo eziphezulu ze-microwave; Ngenxa yesantya sokufuduka kwe-electron ephezulu, inokwenziwa kwiintlobo ngeentlobo zezixhobo eziphezulu (i-RF kunye ne-microwave);I-silicon carbidengumqhubi olungileyo wobushushu kwaye uqhuba ubushushu ngcono kunayo nayiphi na enye imathiriyeli ye-semiconductor, eyenza izixhobo ze-silicon carbide zisebenze kumaqondo obushushu aphezulu.

Njengomzekelo othile, i-APEI ngoku ilungiselela ukuphuhlisa inkqubo yayo yokuqhuba imoto ye-DC ye-NASA's Venus Explorer (VISE) isebenzisa i-silicon carbide components. Kusekwinqanaba loyilo, injongo kukubeka iirobhothi zokuhlola kumphezulu weVenus.

Ukongeza, isilicon carbideinebhondi eyomeleleyo ye-ionic covalent, inobunzima obuphezulu, i-thermal conductivity phezu kobhedu, ukusebenza kakuhle kokuchithwa kobushushu, ukuxhathisa ukubola kunamandla kakhulu, ukuxhathisa kwi-radiation, ukumelana nobushushu obuphezulu kunye nokuzinza okulungileyo kweekhemikhali kunye nezinye iipropati, unoluhlu olubanzi lwezicelo kwindawo icandelo letekhnoloji ye-aerospace. Ngokomzekelo, ukusetyenziswa kwezinto ze-silicon carbide ukulungiselela i-spacecraft ye-astronauts, abaphandi ukuba baphile kwaye basebenze.
