4H-semi HPSI 2inch SiC gawo laling'ono laling'ono Lopanga Dummy Research kalasi
Semi-insulating silicon carbide gawo lapansi zowotcha za SiC
Silicon carbide gawo lapansi makamaka anawagawa conductive ndi theka-amateteza mtundu, conductive pakachitsulo carbide gawo lapansi kwa n-mtundu gawo lapansi makamaka ntchito epitaxial GaN ofotokoza LED ndi zipangizo optoelectronic zipangizo, SiC ofotokoza mphamvu zamagetsi zipangizo, etc., ndi theka- Insulating SiC silicon carbide gawo lapansi limagwiritsidwa ntchito makamaka popanga epitaxial ya GaN yamagetsi yamagetsi yamagetsi apamwamba kwambiri. Kuphatikiza apo, HPSI ndi SI theka-insulation ndi yosiyana, 3.5 * 1013 ~ 8 * 1015 / cm3, yokhala ndi mayendedwe apamwamba a elekitironi; semi-insulation ndi zida zolimba kwambiri, resistivity ndizokwera kwambiri, zomwe zimagwiritsidwa ntchito ngati magawo a chipangizo cha microwave, osagwiritsa ntchito.
Semi-insulating Silicon Carbide gawo lapansi pepala SiC chowotcha
Kapangidwe ka kristalo ka SiC kumatsimikizira thupi lake, logwirizana ndi Si ndi GaAs, SiC ili ndi mawonekedwe akuthupi; oletsedwa gulu m'lifupi ndi lalikulu, pafupi 3 nthawi za Si, kuonetsetsa kuti chipangizo ntchito pa kutentha kwambiri pansi kudalirika kwa nthawi yaitali; kusweka kumunda mphamvu ndi mkulu, ndi 1O nthawi Si, kuonetsetsa kuti chipangizo voteji mphamvu, kusintha chipangizo voteji mtengo; machulukitsidwe elekitironi mlingo waukulu, ndi 2 nthawi Si, kuonjezera chipangizo pafupipafupi ndi mphamvu kachulukidwe; Kutentha kwamafuta kumakhala kwakukulu, kuposa Si, kutentha kwa kutentha kumakhala kwakukulu, kutentha kwa kutentha kumakhala kwakukulu, kutentha kwapamwamba kumakhala kokwera kwambiri, kuposa Si, kutsekemera kwamafuta kumakhala kwakukulu, kutentha kwapamwamba kumakhala kokwera kwambiri. High matenthedwe madutsidwe, kuposa 3 nthawi Si, kuwonjezera kutentha dissipation mphamvu ya chipangizo ndi kuzindikira miniaturization chipangizo.
