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.

Function of Porous Carbon Electrode during the Fabrication of Multiporous-Layered-Electrode Perovskite Solar Cells

Photonics, 2020
We demonstrate the effect of sheet conductivity and infiltration using the example of two graphite types, showing that, in general, the graphite type is very important. Amorphous and pyrolytic graphite were applied to carbon electrodes in fully printable

Charge storage in mesoscopic graphitic islands fabricated using AFM bias lithography [PDF]

, 2011
Electrochemical oxidation and etching of highly oriented pyrolytic graphite (HOPG) has been achieved using biased atomic force microscopy (AFM) lithography, allowing patterns of varying complexity to be written into the top layers of HOPG.

Optical control and manipulation of diamagnetically levitated pyrolytic graphite

AIP Advances, 2019
When levitating above an alternating-pole permanent magnet array, pyrolytic graphite can be displaced by asymmetric diamagnetic forces resulting from optically-induced, localized temperature changes and the thermal dependence of pyrolytic graphite’s ...

Fundamental Study for a Graphite-Based Microelectromechanical System

Micromachines, 2018
We aimed to develop a process for constructing a carbon-based microelectromechanical system (MEMS). First, we prepared a highly oriented pyrolytic graphite (HOPG) crystal microsheet by exfoliation.

Fabrication of multi-layer graphene by repeated transfer

AIP Advances, 2022
Multi-layer graphene was formed by repeated transfer onto a silicon oxide substrate, and changes in its doping characteristics were observed. The structure of multi-layer graphene was investigated in comparison with pyrolytic graphite with a turbostratic
