| Outline of Final Research Achievements |
Dirac electron systems are realized in the surface states of bismuth compound materials, which are also known as excellent thermoelectric materials. Quantum confinement systems have been shown to improve thermoelectric properties. In this project, we investigate electronic and thermoelectric properties of Dirac electrons systems in various quantum confinement systems. In quantum dot systems with Dirac electrons, sharp density of states in the quantum dots appear and excellent thermoelectric characteristics are obtained. A numerical model is proposed to explain various experimental results on the surface state of bismuth thin films.
