Thermopower in parallel double quantum dots with Rashba spin–orbit interaction

doi:10.1088/1674-1056/20/2/027301

Abstract Based on the Green's function technique and the equation of motion approach, this paper theoretically studies the thermoelectric effect in parallel coupled double quantum dots (DQDs), in which Rashba spin–orbit interaction is taken into account. Rashba spin–orbit interaction contributions, even in a magnetic field, are exhibited obviously in the double quantum dots system for the thermoelectric effect. The periodic oscillation of thermopower can be controlled by tunning the Rashba spin–orbit interaction induced phase. The interesting spin-dependent thermoelectric effects will arise which has important influence on thermoelectric properties of the studied system.

Keywords: quantum dot thermopower Rashba spin–orbit interaction spin-dependent inter-dot coupling
