Bophara ba silicon carbide nanowires hangata bo ka tlase ho 500nm, 'me bolelele bo ka fihla ho makholo a μm, e nang le karolo e phahameng ho feta litelu tsa silicon carbide.

Silicon carbide nanowires e rua thepa e fapaneng ea mochini oa thepa e ngata ea silicon carbide hape e na le thepa e mengata e ikhethang ho lisebelisoa tse tlase. Ka khopolo, modulus ea Bacha ea SiCNWs e le 'ngoe e ka ba 610 ~ 660GPa; matla a ho koba a ka fihla ho 53.4GPa, e leng hoo e ka bang habeli ea litelu tsa SiC; matla a thata a feta 14GPa.

Ho phaella moo, kaha SiC ka boeona ke thepa ea semiconductor e sa tobang ea bandgap, ho tsamaea ha elektronike ho phahame. Ho feta moo, ka lebaka la boholo ba nano scale, SiC nanowires e na le phello e nyenyane ea boholo 'me e ka sebelisoa e le lisebelisoa tsa luminescent; ka nako e ts'oanang, SiC-NWs e boetse e bonts'a liphello tsa quantum 'me e ka sebelisoa e le thepa ea catalytic ea semiconductor. Lithapo tsa Nano silicon carbide li na le bokhoni ba ts'ebeliso masimong a tlhahiso ea masimong, lisebelisoa tse matlafatsang le tse thata, li-supercapacitor le lisebelisoa tsa ho monya maqhubu a motlakase.

Sebakeng sa tlhahiso ea tšimo, hobane lithapo tsa nano SiC li na le conductivity e ntle ea mocheso, bophara ba lekhalo la sehlopha se seholo ho feta 2.3 eV, le ts'ebetso e ntle ea tlhahiso ea masimong, li ka sebelisoa ho li-chips tse kopaneng tsa potoloho, lisebelisoa tsa vacuum microelectronic, jj.
Silicon carbide nanowires e 'nile ea sebelisoa e le lisebelisoa tsa ho susumetsa. Ka ho teba ha lipatlisiso, butle-butle li ntse li sebelisoa ho photochemical catalysis. Ho na le liteko tse sebelisang silicon carbide nanowires ho etsa liteko tsa sekhahla sa acetaldehyde, le ho bapisa nako ea ho bola ha acetaldehyde ho sebelisa mahlaseli a ultraviolet. E paka hore silicon carbide nanowires e na le thepa e ntle ea photocatalytic.

Kaha bokaholimo ba SiC nanowires bo ka theha sebaka se seholo sa sebopeho sa mekhahlelo e 'meli, e na le ts'ebetso e ntle ea polokelo ea matla a electrochemical mme e sebelisitsoe ho li-supercapacitor.
