  Recent angle resolved photoemission spectrascope (ARPES) experiments on
strongly underdoped Bi$_2$Sr$_{2-x}$La$_x$CuO$_{6+\delta}$ cuprates have
reported an unusual gap in the nodal direction. Transport experiments on these
cuprates found variable range hopping behavior observed. These cuprates have
both electron and hole doping which has led to proposals that this cuprate is
analogous to a partially compensated semiconductors. The nodal gap then
corresponds to the Efros-Schklovskii(ES) gap in such semiconductors. We
calculate the doping dependence and temperature dependence of a ES gap model
and find support for an Efros-Schklovskii model.
