| Research Abstract |
To reveal the mechanism of quantum thermoelectric effect in a magnetic field, we established both theories and experiments. We obtained the following results :(i) estimation of Nernst coefficients for Bi using the theory of"phonon drag",(ii) proposal of rectification effect in metal-semiconductor junction,(iii) measurement of Nernst voltage for GaAs/AlGaAs,(iv) development of simulation for transport equation of electric and heat currents, and(v) measurement of transport coefficients of Bi nano-wire.
