Measurement of graphite tight-binding parameters using high-field magnetoreflectance

Magnetic subbands of graphite have been investigated by magneto-infrared reflectance spectroscopy at 4 K in fields up to 31 T. Both Schrodinger-like (K-point) and Dirac-like (H-point) Landau level transitions have been observed, and their magnetic field dependence is analyzed by a newly derived limiting case of the Slonczewski-Weiss-McClure model. The values of the band parameters are evaluated without using sophisticated conductivity peak line-shape analysis. In this work, several less-explored band parameters are determined from the experimental results, and they are known to result in electron-hole asymmetry and the opening of an energy gap between the electron and hole bands in multilayer and bilayer graphene systems.
