Idayamitha yesilicon carbide nanowires ngokuqhelekileyo ingaphantsi kwe-500nm, kwaye ubude bunokufikelela kumakhulu e-μm, enomlinganiselo ophezulu we-aspect ratio kune-silicon carbide whiskers.

I-Silicon carbide nanowires izuza ilifa leepropathi ezahlukeneyo zoomatshini be-silicon carbide isambuku semathiriyeli kwaye zineempawu ezininzi ezizodwa kwizinto ezinomgangatho ophantsi. Ngokwethiyori, imodyuli yeNtsha yeSiCNWs enye imalunga ne-610 ~ 660GPa; amandla okugoba anokufikelela kwi-53.4GPa, emalunga nokuphindwe kabini kunamabhovu e-SiC; amandla okuqina adlula i-14GPa.

Ukongeza, ekubeni i-SiC ngokwayo iyimpahla ye-semiconductor ye-bandgap engathanga ngqo, ukuhamba kwe-electron kuphezulu. Ngaphezu koko, ngenxa yobukhulu bayo be-nano scale, i-SiC nanowires inesiphumo esincinci kwaye ingasetyenziselwa njengento yokukhanya; ngexesha elifanayo, i-SiC-NWs iphinda ibonise imiphumo ye-quantum kwaye ingasetyenziswa njenge-semiconductor catalytic material. Iingcingo zeNano silicon carbide zinamandla okusebenza kumasimi okukhutshwa kwentsimi, ukuqinisa kunye nezixhobo eziqinisayo, ii-supercapacitors, kunye nezixhobo zokufunxa amaza ombane.

Kwintsimi yokukhutshwa kwentsimi, kuba iingcingo ze-nano SiC zine-conductivity egqwesileyo ye-thermal, ububanzi be-gap band ngaphezu kwe-2.3 eV, kunye nokusebenza kakuhle kokukhutshwa kwentsimi, zinokusetyenziswa kwiitshiphusi zesekethe ezidibeneyo, izixhobo ze-vacuum microelectronic, njl.
I-silicon carbide nanowires isetyenziswe njengezinto zokuncedisa. Ngokunzulu kophando, ngokuthe ngcembe zisetyenziswa kwi-photochemical catalysis. Kukho imifuniselo esebenzisa i-silicon carbide nanowires ukwenza umfuniselo we-catalytic rate kwi-acetaldehyde, kwaye uthelekise ixesha lokubola kwe-acetaldehyde usebenzisa imisebe ye-ultraviolet. Ingqina ukuba i-silicon carbide nanowires ineempawu ezintle zefotocatalytic.

Kuba umphezulu we-SiC nanowires unokwenza indawo enkulu yolwakhiwo oluphindwe kabini, inomsebenzi ogqwesileyo wokugcinwa kwamandla e-electrochemical kwaye isetyenziswe kwii-supercapacitors.
