Abstract

Different behaviors of the normal-state resistivity have been observed in (110)-, (113)- and a-oriented YBa2Cu3O7-δ thin films under 200 keV H+ irradiation. It suggests that the c-axis electrical conduction is very sensitive to nonoxygen point defects and a ”semiconductor-metal” phase transition could be induced at very low densities of these defects.
