The origin of electron-hole asymmetry in graphite
P. Plochocka, P. Y. Solane, R. J. Nicholas +5
The electron hole asymmetry has been measured in natural graphite using magneto-optical absorption measurements. A splitting is observed for the transitions at both the -point a…
Carrier dynamics in epitaxial graphene close to the Dirac point
Stephan Winnerl, Milan Orlita, Paulina Plochocka +10
We study the carrier dynamics in epitaxially grown graphene in the range of photon energies from 10 - 250 meV. The experiments complemented by microscopic modeling reveal that the…
High field magneto-transmission investigation of natural graphite
N. Ubrig, P. Plochocka, P. Kossacki +4
Magneto-transmission measurements in magnetic fields in the range B=20-60T have been performed to probe the H and K-point Landau level transitions in natural graphite. At the H-poi…
