Metal to insulator transition in epitaxial graphene induced by molecular doping
S. Y. Zhou, D. A. Siegel, A. V. Fedorov +1
The capability to control the type and amount of charge carriers in a material and, in the extreme case, the transition from metal to insulator is one of the key challenges of mode…
Origin of the energy bandgap in epitaxial graphene
S. Y. Zhou, D. A. Siegel, A. V. Fedorov +4
We studied the effect of quantum confinement on the size of the band gap in single layer epitaxial graphene. Samples with different graphene terrace sizes are studied by using low…
Departure from the conical dispersion in epitaxial graphene
S. Y. Zhou, D. A. Siegel, A. V. Fedorov +1
The pi bands of epitaxially grown graphene are studied by using high resolution angle resolved photoemission spectroscopy. Clear deviations from the conical dispersion expected for…
Coexistence of sharp quasiparticle dispersions and disorder features in graphite
S. Y. Zhou, G. -H. Gweon, C. D. Spataru +4
Angle resolved photoelectron spectroscopy (ARPES) on azimuthally disordered graphite demonstrates that sharp quasiparticle dispersions along the radial direction can coexist with a…
