Txoj kab uas hla ntawm silicon carbide nanowires feem ntau tsawg dua 500nm, thiab qhov ntev tuaj yeem ncav cuag ntau pua μm, uas muaj qhov sib piv ntau dua li silicon carbide whiskers.

Silicon carbide nanowires tau txais ntau yam khoom siv ntawm silicon carbide bulk cov ntaub ntawv thiab tseem muaj ntau yam khoom tshwj xeeb rau cov khoom siv qis. Raws li txoj cai, tus Young's modulus ntawm ib zaug SiCNWs yog hais txog 610 ~ 660GPa; lub zog dabtsi yog khoov tuaj yeem ncav cuag 53.4GPa, uas yog kwv yees li ob zaug ntawm SiC whiskers; lub zog tensile tshaj 14GPa.

Tsis tas li ntawd, txij li SiC nws tus kheej yog ib qho khoom siv tsis ncaj nraim bandgap semiconductor, electron txav tau siab. Ntxiv mus, vim nws cov nano nplai loj, SiC nanowires muaj cov nyhuv me me thiab tuaj yeem siv los ua cov khoom siv luminescent; Tib lub sijhawm, SiC-NWs kuj qhia txog cov teebmeem quantum thiab tuaj yeem siv los ua cov khoom siv semiconductor catalytic. Nano silicon carbide xov hlau muaj peev xwm siv tau nyob rau hauv thaj tsam ntawm thaj chaw emission, kev txhawb zog thiab cov ntaub ntawv toughening, supercapacitors, thiab electromagnetic yoj khoom siv.

Nyob rau hauv lub tshav pob emission, vim hais tias nano SiC xov hlau muaj zoo thermal conductivity, ib tug band sib txawv dav dua 2.3 eV, thiab zoo heev teb emission kev ua tau zoo, lawv yuav siv tau nyob rau hauv integrated circuit chips, nqus microelectronic li, thiab lwm yam.
Silicon carbide nanowires tau siv los ua cov khoom siv catalyst. Nrog rau qhov tob ntawm kev tshawb fawb, lawv tau maj mam siv hauv photochemical catalysis. Muaj cov kev sim siv silicon carbide nanowires los ua qhov kev sim catalytic ntawm acetaldehyde, thiab sib piv lub sij hawm ntawm acetaldehyde decomposition siv ultraviolet rays. Nws ua pov thawj tias silicon carbide nanowires muaj cov khoom zoo photocatalytic.

Txij li cov nto ntawm SiC nanowires tuaj yeem tsim thaj tsam loj ntawm ob txheej txheej txheej, nws muaj cov khoom siv hluav taws xob zoo heev thiab tau siv hauv supercapacitors.
