N-Type SiC Composite Substrates Dia6inch Monocrystaline wapamwamba kwambiri komanso gawo lapansi labwino kwambiri

Dzina la "N-mtundu" limatanthawuza mtundu wa doping womwe umagwiritsidwa ntchito muzinthu za SiC. Mu semiconductor physics, doping imaphatikizapo kuyambitsa mwadala zonyansa mu semiconductor kuti asinthe mphamvu zake zamagetsi. Doping yamtundu wa N imayambitsa zinthu zomwe zimapereka ma elekitironi aulere ochulukirapo, zomwe zimapangitsa kuti zinthuzo zikhale zovuta kunyamula.

Ubwino wa magawo amtundu wa N-SiC ndi awa:

1. Kutentha kwapamwamba: SiC imakhala ndi kutentha kwapamwamba kwambiri ndipo imatha kugwira ntchito pa kutentha kwakukulu, ndikupangitsa kuti ikhale yoyenera kugwiritsira ntchito magetsi amphamvu kwambiri komanso othamanga kwambiri.

2. Mpweya wothamanga kwambiri: Zida za SiC zimakhala ndi mphamvu zowonongeka kwambiri, zomwe zimawathandiza kuti azitha kupirira madera akuluakulu a magetsi popanda kuwonongeka kwa magetsi.

3. Kukana kwa Chemical ndi chilengedwe: SiC ndi yolimbana ndi mankhwala ndipo imatha kupirira zovuta zachilengedwe, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazovuta.

4. Kuchepetsa mphamvu yamagetsi: Poyerekeza ndi zida zachikhalidwe za silicon, magawo a SiC amathandizira kutembenuka kwamphamvu kwamphamvu ndikuchepetsa kutayika kwa mphamvu pazida zamagetsi.

5. Wide bandgap: SiC ili ndi bandgap yotakata, yomwe imalola kuti pakhale zipangizo zamagetsi zomwe zimatha kugwira ntchito pa kutentha kwakukulu komanso mphamvu zambiri.

Ponseponse, magawo ophatikizika a N-mtundu wa SiC amapereka zabwino zambiri pakupanga zida zamagetsi zogwira ntchito kwambiri, makamaka m'mapulogalamu omwe ntchito yotentha kwambiri, kuchuluka kwamphamvu kwamagetsi, komanso kutembenuka kwamphamvu kwamagetsi ndikofunikira.
