Query: Tunnel and thermal c-axis transport in BSCCO in the normal and pseudogap
  state   We consider the problem of c-axis transport in double-layered cuprates, in
particular with reference to Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+\delta}$
compounds. We exploit the effect of the two barriers on the thermal and tunnel
transport. The resulting model is able to describe accurately the normal state
c-axis resistivity in Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+\delta}$, from the
underdoped side up to the strongly overdoped. We extend the model, without
introducing additional parameters, in order to allow for the decrease of the
barrier when an external voltage bias is applied. The extended model is found
to describe properly the c-axis resistivity for small voltage bias above the
pseudogap temperature $T^{*}$, the c-axis resistivity for large voltage bias
even below $T_c$, and the differential $dI/dV$ curves taken in mesa structures.
