Query: Thermal correction to resistivity of 2D electron (hole) gas in
  low-temperature measurements at B=0   We calculate the zero magnetic field resistivity, taking into account the
degeneracy of the 2D electron (hole) gas and the thermal correction due to the
combined Peltier and Seebeck effects. The resistivity is found to be universal
function of temperature, expressed in units of $\frac{h}{e^{2}}%
(k_{F}l)^{-1}$.
