  We explore the conditions for chiral symmetry breaking in reduced (or pseudo)
quantum electrodynamics at finite temperature in connection with graphene and
other 2D-materials with an underlying Dirac behavior of the charge carriers. By
solving the corresponding Schwinger-Dyson equation in rainbow approximation, in
a Landau-like gauge and neglecting wavefunction renormalization effects, we
find the need of the coupling to exceed a critical value $\alpha_c$ in order
for chiral symmetry to be broken, in agreement with known results from other
groups. In this supercritical regime, we add the effects of a thermal bath at
temperature $T$ and find the critical values of this parameter that leads to
chiral symmetry restoration.
