For instance, the band-gap for SiC ranges from 2.2 eV for 3C-SiC to 3.2 eV for 4H-SiC. Since 4H-SiC has higher electron mobility than 6H-SiC, it is a preferable option for SiC-based devices. Due to that the thermal conductivity of SiC, which is three times that of Si, and it is expected to withstand higher operating temperature for devices equipped with SiC material.
