Spontaneous formation of metallic nanostructures on highly oriented pyrolytic graphite (HOPG): an ab initio and experimental study
(Royal Society of Chemistry, 2014-05)
We have investigated the decoration of step-edges of HOPG by Ag, Au and Pt using experimental and theoretical approaches. Metallic nanowires can be formed on bare or functionalized step-edges. Energy dispersion analysis ...
Disorder in H+-irradiated HOPG: Effect of impinging energy and dose on Raman D-band splitting and surface topography
(Beilstein-Institut, 2018-10-19)
Disorder was induced in pristine highly oriented pyrolytic graphite (HOPG) by irradiation with H+ ions with energies of 0.4 MeV and 1 MeV, and doses of 1014 ions/cm2 and 1016 ions/cm2. Raman spectroscopy was used as the ...
Estudio de materiales nanoestructurados mediante microscopia de efecto túnel
(2011-03-14)
En esta tesis se estudian dos tipos de superficies nanoestructuradas, generadas sobre muestras de grafito pirolítico altamente orientado (HOPG, del inglés highly oriented pyrolytic graphite) luego de ser bombardeada con ...
Magneto-transport Properties Of As-implanted Highly Oriented Pyrolytic Graphite
(Elsevier Science BVAmsterdam, 2016)
Low energy ion scattering in He/HOPG system
(Elsevier Science, 2008-02)
Low energy ion scattering (LEIS) is a unique tool in surface analysis, since it provides the atomic composition of the outer atomic layer, and time of flight ion scattering (TOF) is a non-destructive method of analysis ...
Structural and magnetic changes induced by electron and ion irradiation on HOPG
(Elsevier, 2015-04)
In recent decades, many studies reported magnetism in carbon-based materials. This phenomenon was attributed to structural defects within the sample. Many authors showed an increase of magnetization in HOPG (Highly Oriented ...
