Ububanzi be-silicon carbide nanowires ngokuvamile bungaphansi kuka-500nm, futhi ubude bungafinyelela kumakhulu ama-μm, ane-aspect ratio ephakeme kunentshebe ye-silicon carbide.
Ama-Silicon carbide nanowires azuza ifa lezinto ezihlukahlukene zemishini ye-silicon carbide ngobuningi bezinto futhi anezici eziningi ezihlukile ezintweni ezinobukhulu obuphansi. Ngokwethiyori, i-modulus ye-Young ye-SiCNWs eyodwa cishe i-610 ~ 660GPa; amandla okugoba angafinyelela ku-53.4GPa, cishe okuphindwe kabili kunamadevu e-SiC; amandla aqinile adlula i-14GPa.
Ngaphezu kwalokho, njengoba i-SiC ngokwayo iyinto engaqondile ye-semiconductor ye-bandgap, ukuhamba kwe-electron kuphezulu. Ngaphezu kwalokho, ngenxa yobukhulu bayo besikali se-nano, i-SiC nanowires inomphumela omncane wesayizi futhi ingasetshenziswa njengento ekhanyayo; ngesikhathi esifanayo, i-SiC-NWs iphinde ibonise imiphumela ye-quantum futhi ingasetshenziswa njengempahla ye-semiconductor catalytic. Izintambo ze-Nano silicon carbide zinamandla okusebenza emikhakheni yokukhishwa kwensimu, ukuqinisa kanye nezinto eziqinisayo, ama-supercapacitor, namadivayisi wokumunca amagagasi kagesi.
Emkhakheni wokukhishwa kwensimu, ngoba izintambo ze-nano SiC zinokusebenza okushisayo okuhle kakhulu, ububanzi begebe lebhendi elikhulu kuno-2.3 eV, nokusebenza okuhle kakhulu kokukhipha insimu, zingasetshenziswa kuma-chips wesekethe ahlanganisiwe, amadivaysi e-vacuum microelectronic, njll.
I-Silicon carbide nanowires isetshenziswe njengezinto zokuvuselela. Ngokujula kocwaningo, kancane kancane asetshenziswa ku-photochemical catalysis. Kukhona ukuhlola okusebenzisa i-silicon carbide nanowires ukwenza izivivinyo ze-catalytic rate ku-acetaldehyde, futhi kuqhathaniswe isikhathi sokubola kwe-acetaldehyde kusetshenziswa imisebe ye-ultraviolet. Kufakazela ukuthi ama-silicon carbide nanowires anezakhiwo ezinhle ze-photocatalytic.
Njengoba ingaphezulu le-SiC nanowires lingakha indawo enkulu yohlaka oluphindwe kabili, linokusebenza okuhle kakhulu kokugcinwa kwamandla kagesi futhi isetshenziswe kuma-supercapacitor.
