Invited review: Graphite and its hidden superconductivity

Pablo Esquinazi

Abstract


We review experimental results, from transport to magnetization measurements, on different graphite samples, from bulk oriented graphite, thin graphite films to transmission electron microscope lamellae, that indicate the existence of granular superconductivity at temperatures above 100~K. The   accumulated evidence speaks for a localization of the superconducting phase(s) at certain interfaces  embedded in semiconducting crystalline regions with Bernal stacking order.
