We have investigated the effects on electrical properties of Al-doped ZnO (AZO) semiconductor films induced by high-energy heavy ion. The AZO films with c-axis on SiO $_{2}$ glass substrate were prepared by a RF-sputter-deposition method at 400 $^{circ}$ C. Rutherford backscattering spectroscopy shows that the Al/Zn composition and the film thickness are 4 % and 0.3 m. We find that the conductivity monotonically increases from 1.510 $^{2}$ to 810 $^{2}$ S/cm with increasing the fluence up to 410 $^{13}$ /cm $^{2}$ , as already been observed for 100 keV Ne irradiation. The fluence of 100 keV Ne at which the conductivity takes its maximum is 310 $^{16}$ /cm $^{2}$ (7 dpa). The dpa of 100 MeV Xe at 410 $^{13}$ /cm $^{2}$ is estimated as 0.008. Hence, the conductivity increase by 100 MeV Xe ion is ascribed to the electronic excitation effects.

We have investigated the effects on electrical and optical properties of Al-doped ZnO (AZO) semiconductor films induced by high-energy heavy ion. The AZO films with c-axis on SiO $_{2}$ glass substrate were prepared by a RF-sputter-deposition method at 400 $^{circ}$ C. Rutherford backscattering spectroscopy shows that the Al/Zn composition and the film thickness are 4 % and 0.3 m. No appreciable change was observed in optical transparency. We find that the conductivity monotonically increases from 1.510 $^{2}$ to 810 $^{2}$ S/cm with increasing the fluence up to 410 $^{13}$ /cm $^{2}$ , as already been observed for 100 keV Ne irradiation. The fluence of 100 keV Ne at which the conductivity takes its maximum is 310 $^{16}$ /cm $^{2}$ (7 dpa). The dpa of 100 MeV Xe at 410 $^{13}$ /cm $^{2}$ is estimated as 0.008.
