Comparing the temperature dependence of the frequency exponent shows that the </span> <span style="font-size:11pt;">correlated
barrier hopping model </span> <span style="font-size:11pt;"> best describes
the experimental data on the ac conductivity in ZnO:Cu thin films. In order to
gain an understanding of the applicability of Meyer-Neldel rule, the dependence
of the thermal activation energy on Cu doping concentration in these films </span> <span style="font-size:11pt;">has
also been studied. The obtained experimental results indicated that
Meyer-Neldel rule can be succesfully applied ac conductivity data for highly Cu
doped films but not others which has been explained on the basis of
distribution variations in density of states. </span> </p> <p> </p>}, number={6}, publisher={Sakarya University}
