Cluster cleaned HOPG by XPS [PDF]

open access: yes, 2017
X-ray photoelectron spectroscopy (XPS) was used to characterize a highly oriented pyrolytic graphite (HOPG) sample. The HOPG was freshly cleaved using scotch tape prior in the entry lock of the spectrometer and subsequently cleaned using an argon ...

The effect of structural disorder on the secondary electron emission of graphite

open access: yesAIP Advances, 2016
The dependance of the secondary electron yield (SEY) on the degree of crystallinity of graphite has been investigated during the amorphization of a highly oriented pyrolytic graphite (HOPG) samples by means of Ar+ bombardment.

Electrochemistry of Graphene Flake Electrodes: Edge and Basal Plane Effect for Biosensing

open access: yesInternational Journal of Electrochemical Science, 2016
In order to study the properties of the graphene basal plane and edge specifically, the graphene flakes (GFs) were selectively masking with a non-conducting polymer to access the basal plane and edge only.

Open STM: A low-cost scanning tunneling microscope with a fast approach method

open access: yesHardwareX
In this study, we have developed an low-cost scanning tunneling microscope (STM) cost of 300 USD or 2000 CNY. The microscope is suitable for educational purposes and low-demand research imaging at the nanometer level.

One-step electrodeposition of ligand-free PdPt alloy nanoparticles from water droplets: Controlling size, coverage, and elemental stoichiometry

open access: yesElectrochemistry Communications, 2019
We present a robust and facile method to produce metal nanoparticle (NP) alloys in a one-step synthesis using direct electrodeposition onto highly oriented pyrolytic graphite (HOPG).

Disorder in H+-irradiated HOPG: effect of impinging energy and dose on Raman D-band splitting and surface topography

open access: yesBeilstein Journal of Nanotechnology, 2018
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.

Low-energy electron diffraction study of potassium adsorbed on single-crystal graphite and highly oriented pyrolytic graphite [PDF]

open access: yes
Potassium adsorption on graphite has been a model system for the understanding of the interaction of alkali metals with surfaces. The geometries of the s232d structure of potassium on both single-crystal graphite (SCG) and highly oriented pyrolytic ...
