| Summary:
We theoretically consider a junction composed of a ferromagnetic insulator
(FI) and a two-dimensional electron gas (2DEG) with Rashba- and
Dresselhaus-type spin-orbit interactions. Using the Boltzmann equation, we
calculate an electric current in 2DEG induced by the inverse Rashba-Edelstein
effect when imposing the temperature difference between FI and 2DEG. We clarify
how the induced current depends on the magnetization direction of FI, spin
texture on the Fermi surface of 2DEG, and temperature. Our result provides an
important foundation for an accurate analysis of the inverse Rashba-Edelstein
effect induced by thermal spin injection.
