Abstract

The interaction between slow highly-charged ions (SHCI) of different charge states from an electron-beam ion trap and highly oriented pyrolytic graphite (HOPG) surfaces is studied in terms of modification of electronic states at single-ion impact nanosizeareas. Results are presented from AFM/STM analysis of the induced-surface topological features combined with Raman spectroscopy. I-V characteristics for a number of different impact regions were measured with STM and the results argue for possible formation of diamond-like nanoscale structures at the impact sites.

Transforming graphite to nanoscale diamonds by a femtosecond laser pulse

Journal Article Nueske, R ; Jurgilaitis, A ; Enquist, H ; ... - Applied Physics Letters

Formation of cubic diamond from graphite following irradiation by a single, intense, ultra-short laser pulse has been observed. Highly oriented pyrolytic graphite (HOPG) samples were irradiated by a 100 fs pulse with a center wavelength of 800 nm. Following laser exposure, the HOPG samples were studied using Raman spectroscopy of the sample surface. In the laser-irradiated areas, nanoscale cubic diamond crystals have been formed. The exposed areas were also studied using grazing incidence x-ray powder diffraction showing a restacking of planes from hexagonal graphite to rhombohedral graphite.

Structural and electronic properties of graphite and graphite intercalation compounds MC[sub 8] (M = K, Rb, Cs) governing their scanning tunneling microscopy images

Journal Article Whangbo, M H ; Liang, W ; Ren, J ; ... - Journal of Physical Chemistry; (United States)

Several puzzling observations in the scanning tunneling microscopy (STM) and atomic force microscopy (AFM) studies of highly oriented pyrolytic graphite (HOPG) and its intercalation compounds MC[sub 8] (M = K, Rb, Cs) were investigated on the basis of atom-atom potential and Coulombic interaction energy calculations. The charge or spin density wave state of a graphite monolayer is found inconsistent with an identical peak registry of the HOPG STM images obtained at plus and minus bias voltages. Simultaneous STM/AFM measurements of HOPG show the STM and AFM images to have an identical peak registry, which implies that the local hardness ofmore »« less

Electronic sputtering and desorption effects in TOF-SIMS studies using slow highly charged ions like Au{sup 69+}

Conference Schenkel, T ; Briere, M A ; Schmidt-Boecking, H ; ...

Secondary ion yields from highly oriented pyrolytic graphite (HOPG) and SiO{sub 2} (native oxide on float zone silicon) targets at impact of slow (v {approx} 0.3 v{sub bohr}) highly charged ions have been measured by Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS). A direct comparison of collisional and electronic effects in secondary ion production using a beam of charge state equilibrated 300 keV Xe{sup 1+} shows a secondary ion yield increase with incident ion charge of {>=}100.

Graphite to diamond transformation under shock compression: Role of orientational order

Journal Article Volz, Travis J. ; Gupta, Y. M. - Journal of Applied Physics

To gain insight into the role of orientational order on the shock-induced graphite to diamond phase transformation, three pyrolytic graphite types having different orientational orders were shock-compressed along the average c-axis to peak stresses between 35 and 69 GPa. The materials studied were ZYB-grade highly oriented pyrolytic graphite (HOPG), ZYH-grade HOPG, and as-deposited pyrolytic graphite (PG) having mosaic spreads of 0.8° ± 0.2°, 3.5° ± 1.5°, and ~45°, respectively. Wave profiles, obtained using laser interferometry, show a multiple-wave structure with a distinct, rapid (<10 ns) rise to the high-pressure phase for each graphite type. Multiple-wave profiles, first observed in thismore »« less

Neutralization and equilibration of highly charged argon ions at grazing incidence on a graphite surface

Journal Article Winecki, S ; Cocke, C L ; Stoeckli, M P ; ... - Bulletin of the American Physical Society

Final charge state distributions of argon ions, scattered grazingly from a smooth highly oriented pyrolytic graphite (HOPG) surface, have been measured as a function of initial charge state (q=4-17) and impact velocity (v=0.15-0.62 a.u.). The final charge state distribution changes strongly with the impact velocity, but is almost independent of the initial charge state. The neutralization during grazing-angle scattering is compared to the charge state equilibration experienced by ions passing through a solid (carbon foil), and these two processes seem to have common properties. A K x-ray spectrum from the K-shell vacancy decay of 51 keV Ar{sup 17+} projectiles wasmore »« less
