ABSTRACTIon beam irradiation of Glassy Carbon is shown to increase its resistivity by up to eight orders of magnitude. These changes in resistivity are correlated with results obtained from Raman spectroscopy and Reflection High Energy Electron Diffraction. At high doses of C implantation there is convincing evidence that ion beam irradiation partially graphitizes the surface of Glassy Carbon.

AbstractThe electrical conductivity of ion beam irradiated Glassy Carbon has been investigated in the temperature range 100 to 300 K. Ion species used were C+ and N+ with doses between 1014 and 1018 ions/cm2. Ion beam irradiation was found to lower the conductivity of Glassy Carbon by up to six orders of magnitude. The temperature dependence of the conductivity in ion beam modified Glassy Carbon has been measured. The functional dependence was found to remain largely unchanged by ion irradiation despite the large overall decrease in the conductivity. The results are interpreted in terms of a model which includes a variable range hopping and strongly scattering metallic components.

We discuss some effects of oxygen ions on a polymer, on the basis of spectroscopic data analysis related to the study of the effect of the space medium in the lower earth orbit (LEO). Oxygen and UV light have an influence upon the surface of spacecraft in LEO. The light transmittance of polymers decreases with time during oxygen ion beam irradiation. The signals of CO2and C=O in the ATR spectra indicate that the surface of the polymer is oxidized and the chain of the polyimide partially cut. When the oxygen ion beam hits the aluminum coated on the polymer, the mass loss of aluminum can be clearly detected by measuring the change of the transmittance.

In this paper, we report the influence of low-energy oxygen ion irradiation with fluence ranging from [Formula: see text][Formula: see text][Formula: see text] to [Formula: see text][Formula: see text][Formula: see text] on the structural, optical, and electrical properties of fresh and annealed (400∘C, 3[Formula: see text]h) zinc oxide (ZnO) thin films. These films were grown on soda-lime glass (SLG) substrates using the spin-coating method as a low-cost depositing technique. X-ray diffraction (XRD) study showed the formation of the hexagonal phase of ZnO thin films with preferred orientation along the (002) plane. The crystallite size for fresh and annealed ZnO thin films was in nanoscale and it increased with the annealing temperature. Also, the crystallite size increased with the ion beam irradiation fluence in the case of annealed ZnO films, while it slightly decreased for the fresh ZnO films. The transmittance and absorbance spectra for the ZnO films were investigated in a wide wavelength range. The optical bandgap was specified by using Tauc’s relation. The electrical properties of the ZnO films (fresh and annealed at 400∘C for 3[Formula: see text]h) were studied before and after the oxygen ion beam irradiation. Also, the dielectric properties were investigated with respect to frequency at different ion beam irradiation fluences. The comprehensive results showed the dielectric and optical properties are improved due to the induced conductive networks by oxygen ion irradiation.
