M'mimba mwake ya silicon carbide nanowires nthawi zambiri imakhala yosakwana 500nm, ndipo kutalika kwake kumatha kufika mazana a μm, omwe ali ndi chiŵerengero chapamwamba kuposa ndevu za silicon carbide.
Silicon carbide nanowires amatenga zinthu zosiyanasiyana zamakina a silicon carbide zochulukira komanso amakhala ndi zinthu zambiri zapadera ndi zida zotsika. Mwachidziwitso, modulus ya Young ya SiCNWs imodzi ili pafupi 610 ~ 660GPa; mphamvu yopindika imatha kufika ku 53.4GPa, yomwe ili pafupifupi kawiri ndevu za SiC; mphamvu yamphamvu imaposa 14GPa.
Komanso, popeza SiC palokha ndi osalunjika bandgap semiconductor zakuthupi, ndi electron kuyenda ndi mkulu. Kuphatikiza apo, chifukwa cha kukula kwake kwa nano, SiC nanowires imakhala ndi mphamvu yaying'ono ndipo imatha kugwiritsidwa ntchito ngati zinthu zowunikira; nthawi yomweyo, SiC-NWs amasonyezanso zotsatira za quantum ndipo angagwiritsidwe ntchito ngati semiconductor catalytic material. Mawaya a Nano silicon carbide ali ndi kuthekera kogwiritsa ntchito m'minda yotulutsa mpweya, zolimbikitsira ndi zolimba, ma supercapacitors, ndi zida zamagetsi zamagetsi zamagetsi.
M'munda wa umuna kumunda, chifukwa mawaya nano SiC ndi madutsidwe kwambiri matenthedwe matenthedwe, gulu kusiyana m'lifupi kuposa 2.3 eV, ndi ntchito yabwino kumunda umuna, angagwiritsidwe ntchito tchipisi Integrated dera, zingalowe zipangizo microelectronic, etc.
Silicon carbide nanowires akhala akugwiritsidwa ntchito ngati zida zothandizira. Ndi kuzama kwa kafukufuku, pang'onopang'ono akugwiritsidwa ntchito mu photochemical catalysis. Pali zoyeserera zogwiritsa ntchito silicon carbide nanowires poyesa kuyesa kwamphamvu pa acetaldehyde, ndikuyerekeza nthawi ya kuwonongeka kwa acetaldehyde pogwiritsa ntchito kuwala kwa ultraviolet. Zimatsimikizira kuti silicon carbide nanowires ali ndi zinthu zabwino za photocatalytic.
Popeza pamwamba pa SiC nanowires imatha kupanga gawo lalikulu la magawo awiri, imakhala ndi ntchito yabwino yosungiramo mphamvu zamagetsi ndipo yakhala ikugwiritsidwa ntchito mu supercapacitors.
