  We theoretically study the thermoelectric transport properties of strained
HgTe in the topological insulator phase. We developed a model for the system
using a Dirac Hamiltonian including the effect of strain induced by the
interface between HgTe and the CdTe substrate. The conductivity tensor was
explored assuming the electrons are scattered by charge impurities, while the
thermopower tensor was addressed using the Mott relation. Seebeck and Nernst
responses exhibit remarkable enhancements in comparison with other
two-dimensional Dirac materials, such as graphene, germanane, prosphorene and
stanene. The intensity of these termoeletric responses, their dependencies with
the external perpendicular magnetic field and temperature are also addressed.
