Studies of electrical resistivity of highly oriented pyrolytic graphite under high pressures at room temperature

Аннотация

The pressure dependence of electrical resistivity of highly oriented pyrolytic graphite is investigated at room temperature. The time needed to stabilize a sample’s resistance at constant pressure ranges from one hour to several days. The influence of the thickness of a sample and a current passed through it on the magnitude and pronouncedness of characteristic features in the pressure dependence of graphite resistance is found.
