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. WebThe Seebeck emf of -SiC substrates and -SiC samples ranges between−9 V C−1 and −108 V C−1 which is higher than that of commercial Pt thermocouples. SiC has a strong potential … WebApr 15, 2010 · The performance of a thermoelectric material is classified by the TE Figure of Merit, ZT = S 2 T / ρκ, where S is the Seebeck coefficient, ...
