London forces in highly oriented pyrolytic graphite

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2017
Surface of highly oriented pyrolytic graphite with terrace steps was studied using scanning tunneling microscopy with high spatial resolution. Spots with positive and negative charges were found in the vicinity of the steps.

Electrodeposition of Two-Dimensional Pt Nanostructures on Highly Oriented Pyrolytic Graphite (HOPG): The Effect of Evolved Hydrogen and Chloride Ions [PDF]

Nanomaterials, 2018
We discuss the electrodeposition of two-dimensional (2D) Pt-nanostructures on Highly Oriented Pyrolytic Graphite (HOPG) achieved under constant applied potential versus a Pt counter electrode (Eappl = ca. −2.2 V vs. NHE, normal hydrogen electrode).

High temperature stability of onion-like carbon vs highly oriented pyrolytic graphite. [PDF]

PLoS ONE, 2014
The thermodynamic stability of onion-like carbon (OLC) nanostructures with respect to highly oriented pyrolytic graphite (HOPG) was determined in the interval 765-1030 K by the electromotive force (emf) measurements of solid electrolyte galvanic cell ...

Highly oriented pyrolytic graphite chemical bonding structure after gallium implantation [PDF]

Scientific Reports
Highly oriented pyrolytic graphite (HOPG) structural changes caused by gallium (Ga) implantation at room temperature were investigated. Ga ions were implanted into HOPG at different energies (10, 20, and 30 keV) and fluences (ranging from 2 × 1015 to 5 ×

Recent studies of highly oriented pyrolytic graphite and hybrid graphite-silicon monochromator systems [PDF]

EPJ Web of Conferences, 2023
The excellent performance of highly oriented pyrolytic graphite (HOPG) as monochromator, analyzer and filter material for neutron instrumentation was discovered more than 50 years ago. Even though HOPG has been in use for a long time, there is still room
