Landau Level Spectroscopy of Rhombohedral Graphite Films

We have seen that at low temperatures, the transport properties of rhombohedral graphite films are dominated by two-dimensional low energy surface states. One of the most powerful techniques to characterise electronic structure of high-quality two-dimensional systems is to study their magnetic field dependence, including the study of quantum Hall effect and carrying out of Landau level spectroscopy experiments. Hence, this chapter will be dedicated to Landau level spectroscopy of the low energy surface states, with the overall goal of gaining a complete understanding of dispersion properties of low energy surface states of rhombohedral graphite films.
