Thermoelectric transport in double-Weyl semimetals
Thermoelectric transport in double-Weyl semimetals
We study the thermoelectric properties of a double-Weyl fermion system, possibly realized in ${\mathrm{HgCr}}_{2}{\mathrm{Se}}_{4}$ and ${\mathrm{SrSi}}_{2}$, by a semiclassical Boltzmann transport theory. We investigate different relaxation processes including short-range disorder and electron-electron interaction on the thermoelectric transport coefficients. It is found that the anisotropy of the band dispersion for in-plane …
