Thermoelectric and Magnetic Properties in Doped FeVAl within a Bipolar Random Anderson Model

Takami Tohyama, Hidetoshi Fukuyama

We investigate the thermoelectric and magnetic properties of Si-substituted -type and Ti-substituted -type Heusler alloy FeVAl using the bipolar random Anderson model, wh…

Effects of Antisite Defects on Seebeck Coefficient in Fe_2VAl -- Analyses based on Bipolar Random Anderson Model

Takami Tohyama, Hidetoshi Fukuyama

A microscopic mechanism is proposed for a dramatic sign change of the Seebeck coefficient from positive to negative sign by the introduction of antisite defects in FeVAl based…

Scaling theory of charge transport and thermoelectric response in disordered 2D electron systems: From weak to strong localization

Takahiro Yamamoto, Hiroki Kaya, Manaho Matsubara +1

We develop a new theoretical scheme for charge transport and thermoelectric response in two-dimensional disordered systems exhibiting crossover from weak localization (WL) to stron…

Two-band Model with High Thermoelectric Power Factor and Its Application to FeSe Thin Film

Manaho Matsubara, Takahiro Yamamoto, Hidetoshi Fukuyama

We propose a simple theoretical model referred to as the {\it two-band model} to realize both a large Seebeck coefficient and high electrical conductivity, resulting in a high ther…
