| Abstract(in English) | In order to obtain the thermoelectric characteristics enough for practical use, we make use of nanostructures in the thermoelectric devices. In this study, we measure the Seebeck coefficient and electrical conductivity of 2-dimensional (2D) Si slab structures fabricated on SOI (silicon on insulator) wafers, and we discuss the effect of the electron confinement on the thermoelectric characteristics. It is found that a 3-nm-thick SOI sample has a higher Seebeck coefficient comparing to other samples with SOI thickness above 6nm. This result suggests that the Seebeck coefficient can be enhanced due to the electron confinement in a 2D quantum well for the SOI samples as thin as 3nm. |
