Izinto ze-semiconductor ze-silicon carbide

I-silicon carbide (i-SiC)Izinto ze-semiconductor zivuthiwe kakhulu phakathi kwama-semiconductor e-wide band gap athuthukiswe. Izinto ze-semiconductor ze-SiC zinamandla amakhulu okusetshenziswa kumadivayisi amelana nokushisa okuphezulu, imvamisa ephezulu, amandla aphezulu, ama-photoelectronics kanye nemisebe ngenxa yesikhala sawo se-wide band, insimu kagesi eqhekeka kakhulu, ukuqhuba okuphezulu kokushisa, ukuhamba kwama-electron okugcwala okuphezulu kanye nosayizi omncane. I-Silicon carbide inezinhlobo eziningi zokusetshenziswa: ngenxa yesikhala sayo se-wide band, ingasetshenziswa ukwenza ama-diode akhipha ukukhanya okuluhlaza okwesibhakabhaka noma ama-ultraviolet detectors angathinteki kakhulu ukukhanya kwelanga; Ngoba insimu ye-voltage noma kagesi ingabekezelelwa izikhathi eziyisishiyagalombili kune-silicon noma i-gallium arsenide, efanelekile kakhulu ekukhiqizeni amadivayisi anamandla aphezulu e-voltage njenge-diode ephezulu ye-voltage, i-power triode, amadivayisi e-microwave alawulwa yi-silicon kanye namadivayisi anamandla aphezulu; Ngenxa yesivinini sokufuduka kwama-electron okugcwala okuphezulu, kungenziwa kube amadivayisi ahlukahlukene emvamisa ephezulu (RF kanye ne-microwave);I-silicon carbideiyisiqhubi esihle sokushisa futhi iqhuba ukushisa kangcono kunanoma yiziphi ezinye izinto ze-semiconductor, okwenza amadivayisi e-silicon carbide asebenze emazingeni okushisa aphezulu.

Njengesibonelo esithile, i-APEI okwamanje ilungiselela ukuthuthukisa uhlelo lwayo lokushayela imoto ye-DC olusendaweni engaphandle kakhulu lwe-Venus Explorer (VISE) ye-NASA isebenzisa izingxenye ze-silicon carbide. Kusesesigabeni sokuklama, umgomo uwukubeka amarobhothi okuhlola ebusweni be-Venus.

Ngaphezu kwalokho, si-icon carbideinesibopho esiqinile se-ionic covalent, inobulukhuni obuphezulu, i-thermal conductivity ngaphezu kwethusi, ukusebenza okuhle kokushabalalisa ukushisa, ukumelana nokugqwala kunamandla kakhulu, ukumelana nemisebe, ukumelana nokushisa okuphezulu kanye nokuqina kwamakhemikhali okuhle nezinye izakhiwo, inezinhlobo eziningi zezicelo emkhakheni wobuchwepheshe bezindiza. Isibonelo, ukusetshenziswa kwezinto ze-silicon carbide ukulungiselela izindiza zasemkhathini ukuze osomkhathi, abacwaningi baphile futhi basebenze.
