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…
Bilayer splitting and c-axis coupling in bilayer manganites showing colossal magnetoresistance
C. Jozwiak, J. Graf, S. Y. Zhou +5
By performing angle-resolved photoemission spectroscopy of the bilayer colossal magnetoresistive (CMR) manganite, , we provide the complete mapping o…
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…
Low energy excitations in graphite: The role of dimensionality and lattice defects
S. Y. Zhou, G. -H. Gweon, A. Lanzara
In this paper, we present a high resolution angle resolved photoemission spectroscopy (ARPES) study of the electronic properties of graphite. We found that the nature of the low en…
First direct observation of Dirac fermions in graphite
S. Y. Zhou, G. -H. Gweon, J. Graf +7
Originating from relativistic quantum field theory, Dirac fermions have been recently applied to study various peculiar phenomena in condensed matter physics, including the novel q…
