Abstract
We have measured the conductivity of a sample of reduced channel‐plate lead glass over the temperature range 25–300 K. The behavior is consistent with conduction by two‐dimensional variable range hopping. From measurements of the thickness of the conducting layer we estimate the wave‐function overlap parameter α−1⩾50 Å and hence from the temperature dependence of the conduction we deduce that the density of states at the Fermi level is less than 4×1017 eV−1 cm−3.Keywords
