  We study the effects caused by Rashba and Dresselhaus spin-orbit coupling
over the thermoelectric transport properties of a single-electron transistor,
viz., a quantum dot connected to one-dimensional leads. Using linear response
theory and employing the numerical renormalization group method, we calculate
the thermopower, electrical and thermal conductances, dimensionless
thermoelectric figure of merit, and study the Wiedemann-Franz law, showing
their temperature maps. Our results for all those properties indicate that
spin-orbit coupling drives the system into the Kondo regime. We show that the
thermoelectric transport properties, in the presence of spin-orbit coupling,
obey the expected universality of the Kondo strong coupling fixed point. In
addition, our results show a notable increase in the thermoelectric figure of
merit, caused by the spin-orbit coupling in the one-dimensional quantum dot
leads.
