  Thermoelectric coefficients of a two dimensional electron gas with the Rashba
spin-orbit interaction are presented here. In absence of magnetic field,
thermoelectric coefficients are enhanced due to the Rashba spin-orbit
interaction. In presence of magnetic field, the thermoelectric coefficients of
spin-up and spin-down electrons oscillate with different frequency and produces
beating patterns in the components of the total thermoelectric power and the
total thermal conductivity. We also provide analytical expressions of the
thermoelectric coefficients to explain the beating pattern formation. We obtain
a simple relation which determines the Rashba SOI strength if the magnetic
fields corresponding to any two successive beat nodes are known from the
experiment.
