Kohn anomaly and interplay of electron-electron and electron-phonon interactions in epitaxial graphene
S. Y. Zhou, D. A. Siegel, A. V. Fedorov +1
The interplay of electron-phonon (el-ph) and electron-electron (el-el) interactions in epitaxial graphene is studied by directly probing its electronic structure. We found a strong…
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…
Substrate-induced band gap opening in epitaxial graphene
S. Y. Zhou, G. -H. Gweon, A. V. Fedorov +6
Graphene has shown great application potentials as the host material for next generation electronic devices. However, despite its intriguing properties, one of the biggest hurdles…
Synthesis and characterization of atomically-thin graphite films on a silicon carbide substrate
E. Rollings, G. -H. Gweon, S. Y. Zhou +7
This paper reports the synthesis and detailed characterization of graphite thin films produced by thermal decomposition of the (0001) face of a 6H-SiC wafer, demonstrating the succ…
