WebThe thermoelectric properties of quasi-one-dimensional TTT(TCNQ)(2) organic crystals have been investigated to assess the prospect of using this type of compound as an n-type thermoelectric material. 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.
