WebThe Seebeck effect in some SiC polytypes was investigated in sixties and seventies. At that time, it was observed that in SiC the Seebeck coefficient exceeds the ones in silicon and germanium. It was believed that the reason for that phenomenon was not only in a simple difference in the bandgap energy but also in a stronger phonon drag effect.
