Conductivity of compensated semimetals with low carrier density in the case of phonon-phonon dragging
Kozlov V.A., Dakhno V.D.
It is shown that when the scattering of electrons and holes from a surface differ in character, a unique hydrodynamic conductivity mechanism is possible and leads to an exponential temperature dependence. The conditions for experimentally observing the effect in real materials are discussed.
