Silicon carbide (SiC) ke lisebelisoa tsa semiconductor tse kopantsoeng tse entsoeng ka likarolo tsa carbon le silicon, 'me ke e' ngoe ea lisebelisoa tse loketseng bakeng sa ho etsa lisebelisoa tsa mocheso o phahameng, oa maqhubu a phahameng, a matla a phahameng le a matla a phahameng. Ha ho bapisoa le thepa e tloaelehileng ea silicon (Si), bophara bo hanetsoeng ba sehlopha sa silicon carbide ke makhetlo a mararo a silicon; conductivity ea mocheso ke makhetlo a 4-5 a silicon; matla a ho senya ke makhetlo a 8-10 a silicon; 'me sekhahla sa ho hoholeha ha elektronike ke makhetlo a 2-3 ho feta a silicon, e kopanang le litlhoko tsa indasteri ea morao-rao bakeng sa matla a phahameng, matla a phahameng, le maqhubu a phahameng,' me e sebelisoa haholo-holo ho etsa lebelo le phahameng, le phahameng- maqhubu, matla a phahameng le likarolo tsa elektronike tse ntšang khanya, 'me libaka tsa eona tsa ts'ebeliso ea tlase ho metsi li kenyeletsa marang-rang a bohlale, likoloi tse ncha tsa matla, matla a moea a photovoltaic, likhokahano tsa 5G, joalo-joalo Lefapheng la lisebelisoa tsa motlakase, li-silicon carbide diode le MOSFET li se li qalile ho ba teng. e sebelisoang ke khoebo.

Melemo ea li-wafers tsa SiC / SiC substrate

Ho hanyetsa mocheso o phahameng. Bophara bo hanetsoeng ba sehlopha sa silicon carbide ke makhetlo a 2-3 ho feta a silicon, kahoo lielektrone ha li na monyetla oa ho tlola mocheso o phahameng 'me li khona ho mamella mocheso o phahameng oa ts'ebetso,' me conductivity ea mocheso oa silicon carbide ke makhetlo a 4-5 ho feta a silicon. ho bonolo ho qhala mocheso ho sesebelisoa le ho lumella mocheso o phahameng oa ho sebetsa o fokolang. Litšobotsi tse phahameng tsa mocheso li ka eketsa matla a matla haholo, ha li ntse li fokotsa litlhoko tsa tsamaiso ea ho senya mocheso, ho etsa hore terminal e be bobebe haholoanyane le e nyenyane.

Ho hanyetsa matla a phahameng. Matla a ts'imo ea silicon carbide ke makhetlo a 10 ho feta a silicon, e e nolofalletsang ho mamella maqhubu a phahameng, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tse phahameng haholo.

Boemo bo phahameng ba ho hanyetsa. Silicon carbide e na le makhetlo a mabeli ho feta tekanyo ea ho hoholeha ha elektronike ea silicon, e leng se etsang hore lisebelisoa tsa eona li kene ka har'a ts'ebetso ea ho koala ha li teng ka mokhoa oa hona joale oa ho hula, li ka ntlafatsa ka katleho mochine oa ho fetola mochine, ho finyella mochine o fokolang.

Tahlehelo e tlase ea matla. Silicon carbide e na le khanyetso e tlase haholo ha e bapisoa le lisebelisoa tsa silicon, tahlehelo e tlase ea conduction; ka nako e ts'oanang, bandwidth e phahameng ea silicon carbide e fokotsa haholo ho lutla hona joale, tahlehelo ea matla; ho phaella moo, lisebelisoa tsa silicon carbide ts'ebetsong ea ho koala ha li teng ka mokhoa oa hona joale oa ho hula, tahlehelo e tlaase ea ho fetoha.
