“…Also for swift heavy ion irradiated ZrO 2 thin films, Moll et al and Sattonnay et al. 59,60 observed tracks consisting of damaged rather than amorphous material with dislocation loops along the ion trajectories. Using Rutherford Backscattering/Channeling and XRD an average track diameter of about 5 -6 nm was determined.…”

We demonstrate the generation of a persistent conductivity increase in vanadium dioxide thin films grown on single crystal silicon by irradiation with 1 GeV 238U swift heavy ions at room temperature. VO2 undergoes a temperature driven metal-insulator-transition (MIT) at 67 °C. After room temperature ion irradiation with high electronic energy loss of 50 keV/nm the conductivity of the films below the transition temperature is strongly increased proportional to the ion fluence of 5·109 U/cm2 and 1·1010 U/cm2. At high temperatures the conductivity decreases slightly. The ion irradiation slightly reduces the MIT temperature. This observed conductivity change is persistent and remains after heating the samples above the transition temperature and subsequent cooling. Low temperature measurements down to 15 K show no further MIT below room temperature. Although the conductivity increase after irradiation at such low fluences is due to single ion track effects, atomic force microscopy (AFM) measurements do not show surface hillocks, which are characteristic for ion tracks in other materials. Conductive AFM gives no evidence for conducting ion tracks but rather suggests the existence of conducting regions around poorly conducting ion tracks, possible due to stress generation. Another explanation of the persistent conductivity change could be the ion-induced modification of a high resistivity interface layer formed during film growth between the vanadium dioxide film and the n-Silicon substrate. The swift heavy ions may generate conducting filaments through this layer, thus increasing the effective contact area. Swift heavy ion irradiation can thus be used to tune the conductivity of VO2 films on silicon substrates

“…However, recent calculations concerning Gd 2 Zr 2 O 7 predict a compaction of the volume of the elementary cell [20]. In c-ZrO 2 , an increase of the lattice parameter with increasing fluence, associated with a macroscopic volume increase was found [14,15]. This increase induces a compressive stress in the irradiated layer and its value increases from À90 MPa to À1100 MPa for Pb fluences in the range 5 Â 10 11 -10 13 cm À2 [14,15,21].…”
