SiC Substrate
Fa'amatalaga
Silicon carbide (SiC) o se tuufaatasiga binary o le Vaega IV-IV, na o le pau lea o le faʻamautu mautu i le Vaega IV o le Vaitaimi Vaitaimi, O se semiconductor taua.O le SiC e sili ona lelei le vevela, masini, vailaʻau ma eletise, lea e avea ai ma se tasi o mea sili ona lelei mo le faʻaogaina o le vevela, maualuga, ma le maualuga o le eletise eletise, o le SiC e mafai foi ona faʻaaogaina e fai ma mea faʻapipiʻi. mo GaN fa'avae moli moli-emitting diodes.I le taimi nei, 4H-SiC o le oloa autu i le maketi, ma o le conductivity ituaiga e vaevaeina i semi-insulating ituaiga ma N ituaiga.
