Very high thermoelectric power factor in a Fe3O4/SiO2/p-type Si(100) heterostructure
Viskadourakis, Z.; Paramês, M. L.; Conde, O.; Zervos, Matthew; Giapintzakis, John (2012)The thermoelectric and transport properties of a Fe3O4/SiO2/p-Si(100) heterostructure have been investigated between 100 and 300 K. Both Hall and Seebeck coefficients change sign from negative to positive with increasing ...
