Ultra-high magnetic field study of the layer split bands in Graphite

Abstract

We report studies of the magnetospectroscopy of graphite into a new regime of high energies and ultra-high magnetic fields which allows us to perform the first spectroscopic studies of the interlayer split off bands, $E_1$ and $E_2$. These bands can be well described by an asymmetric bilayer model and have only a small interlayer band gap asymmetry. We show that all of the properties of the electrons and holes can be described by a simple relativistic behaviour determined by ${\gamma }_0$ and ${\gamma }_1$.
