respectively. The large discrepancy in experimental values of β
listed in Table 1 and
theoretical values of β and
P
β leads to a conclusion that current transport mechanism in
our samples governing the high field at a temperature range of 320K-370K cannot be
explained in terms of Shottky or Poole-Frenkel emission.
