  In this review, the thermoelectric properties in nodal-point semimetals with
two bands are discussed. For the two-dimensional (2D) cases, it is shown that
the expressions of the thermoelectric coefficients take different values
depending on the nature of the scattering mechanism responsible for transport,
by considering examples of short-ranged disorder potential and screened charged
impurities. An anisotropy in the energy dispersion spectrum invariably affects
the thermopower quite significantly, as illustrated by the results for a node
of semi-Dirac semimetal and a single valley of graphene. The scenario when a
magnetic field of magnitude $B$ is applied perpendicular to the plane of the 2D
semimetal is also considered. The computations for three-dimensional (3D) cases
necessarily involve the inclusion of nontrivial Berry phase effects. In
addition to demonstrating the expressions for the response tensors, the exotic
behaviour observed in planar Hall and planar thermal Hall set-ups is also
discussed.
