4H-semi HPSI 2inch SiC substrate wafer Production Dummy Research grade

Gawo la silicon carbide limagawidwa makamaka m'magulu oyendetsera ndi oteteza pang'ono, gawo la silicon carbide loyendetsa pang'ono mpaka gawo la n-mtundu limagwiritsidwa ntchito makamaka pa epitaxial GaN-based LED ndi zida zina zamagetsi, zida zamagetsi zamagetsi zochokera ku SiC, ndi zina zotero, ndipo gawo la silicon carbide loteteza pang'ono la SiC limagwiritsidwa ntchito makamaka popanga zida zamagetsi zamagetsi zamagetsi za GaN. Kuphatikiza apo, kutchinjiriza pang'ono kwapamwamba kwa HPSI ndi SI semi-insulation ndi kosiyana, kutchinjiriza pang'ono kwapamwamba kwapamwamba kwa 3.5 * 1013 ~ 8 * 1015/cm3, ndi kuyenda kwakukulu kwa ma elekitironi; kutchinjiriza pang'ono ndi zinthu zotsutsa kwambiri, kutchinjiriza kumakhala kwakukulu kwambiri, nthawi zambiri kumagwiritsidwa ntchito pazida zamagetsi zama microwave, osati koyendetsa.

Semi-insulating Silicon Carbide substrate sheet SiC wafer

Kapangidwe ka kristalo ka SiC kamatsimikizira kuti kali ndi mphamvu, poyerekeza ndi Si ndi GaAs, ndipo SiC ili ndi mphamvu zakuthupi; m'lifupi mwa band yoletsedwa ndi yayikulu, pafupifupi nthawi zitatu kuposa Si, kuonetsetsa kuti chipangizocho chikugwira ntchito kutentha kwambiri pansi pa kudalirika kwa nthawi yayitali; mphamvu yamunda wosweka ndi yayikulu, ndi nthawi 1O kuposa Si, kuonetsetsa kuti mphamvu yamagetsi ya chipangizocho, ikukweza mphamvu yamagetsi ya chipangizocho; kuchuluka kwa ma elekitironi okhuta ndi kwakukulu, ndi nthawi ziwiri kuposa Si, kuti chiwonjezere kuchuluka kwa ma frequency ndi mphamvu ya chipangizocho; kutentha kopitilira muyeso kuli kwakukulu, kuposa Si, kutentha kopitilira muyeso kuli kwakukulu, kutentha kopitilira muyeso kuli kwakukulu, kutentha kopitilira muyeso kuli kwakukulu, kutentha kopitilira muyeso kuli kwakukulu, kutentha kopitilira muyeso kuli kwakukulu, kuposa Si, kutentha kopitilira muyeso kuli kwakukulu, kutentha kopitilira muyeso kuli kwakukulu. Kutentha kopitilira muyeso kuli kwakukulu, kuposa nthawi zitatu kuposa Si, kukulitsa mphamvu yotaya kutentha ya chipangizocho ndikuzindikira kuchepa kwa mphamvu ya chipangizocho.
