Zonyamula za SiC Coated Graphite，zophimba sic,zophimba SiC zophimbidwa ndi gawo la Graphite la Semiconductor

Chokutidwa ndi silicon carbideDisiki ya graphite ndi yokonzekera gawo loteteza la silicon carbide pamwamba pa graphite pogwiritsa ntchito nthunzi yeniyeni kapena mankhwala ndi kupopera. Gawo loteteza la silicon carbide lokonzedwa likhoza kulumikizidwa mwamphamvu ku matrix ya graphite, zomwe zimapangitsa kuti pamwamba pa maziko a graphite pakhale pokhuthala komanso opanda voids, zomwe zimapatsa matrix ya graphite zinthu zapadera, kuphatikizapo kukana okosijeni, kukana asidi ndi alkali, kukana kukokoloka kwa nthaka, kukana dzimbiri, ndi zina zotero. Pakadali pano, chophimba cha Gan ndi chimodzi mwazinthu zabwino kwambiri pakukulitsa epitaxial ya silicon carbide.

Silicon carbide semiconductor ndiye chinthu chachikulu cha semiconductor yatsopano yopangidwa ndi wide band gap. Zipangizo zake zili ndi mawonekedwe a kukana kutentha kwambiri, kukana magetsi ambiri, ma frequency ambiri, mphamvu zambiri komanso kukana ma radiation. Ili ndi ubwino wosintha mwachangu komanso kugwira ntchito bwino. Imatha kuchepetsa kwambiri kugwiritsa ntchito mphamvu zamagetsi, kusintha mphamvu ndikuchepetsa kuchuluka kwa zinthu. Imagwiritsidwa ntchito kwambiri mu 5g yolumikizirana, chitetezo cha dziko ndi makampani ankhondo. RF field yomwe imayimiridwa ndi ndege ndi magetsi zamagetsi omwe amayimiridwa ndi magalimoto atsopano amphamvu ndi "zomangamanga zatsopano" ali ndi mwayi wowonekera bwino komanso waukulu pamsika m'magawo onse a boma ndi ankhondo.

Chitsulo cha silicon carbide ndiye chinthu chachikulu cha semiconductor yatsopano ya wide band gap. Chitsulo cha silicon carbide chimagwiritsidwa ntchito kwambiri mu zamagetsi a microwave, zamagetsi zamagetsi ndi zina.Ili kumapeto kwa unyolo wa semiconductor wa wide band gap ndipo ndi chinthu chapamwamba komanso chofunikira kwambiri. Silicon carbide substrate ingagawidwe m'mitundu iwiri: semi insulation ndi conductive. Pakati pawo, semi insulation silicon carbide substrate ili ndi resistivity yapamwamba (resistivity ≥ 105 Ω· cm). Semi insulation substrate yophatikizidwa ndi gallium nitride epitaxial sheet yosiyana ingagwiritsidwe ntchito ngati zipangizo za RF, zomwe zimagwiritsidwa ntchito kwambiri pakulankhulana kwa 5g, chitetezo cha dziko ndi makampani ankhondo m'mawonekedwe omwe ali pamwambapa; China ndi conductive silicon carbide substrate yokhala ndi resistivity yotsika (resistivity range ndi 15 ~ 30m Ω· cm). Epitaxy yofanana ya conductive silicon carbide substrate ndi silicon carbide ingagwiritsidwe ntchito ngati zipangizo zamagetsi. Zochitika zazikulu zomwe zimagwiritsidwa ntchito ndi magalimoto amagetsi, makina amagetsi ndi magawo ena.
