Functionalized graphene as a model system for the two-dimensional metal-insulator transition
M. S. Osofsky, S. C. Hernández, A. Nath +4
Reports of metallic behavior in two-dimensional (2D) systems such as high mobility metal-oxide field effect transistors, insulating oxide interfaces, graphene, and MoS2 have challe…
Graphene Manipulation on 4H-SiC(0001) Using Scanning Tunneling Microscopy
P. Xu, M. L. Ackerman, S. D. Barber +8
Atomic-scale topography of epitaxial multilayer graphene grown on 4H-SiC(0001) was investigated using scanning tunneling microscopy (STM). Bunched nano-ridges ten times smaller tha…
Atomic-Scale Movement Induced in Nano-Ridges by Scanning Tunneling Microscopy on Epitaxial Graphene Grown on 4H-SiC(0001)
P. Xu, S. D. Barber, J. K. Schoelz +8
Nanoscale ridges in epitaxial multilayer graphene grown on the silicon face of 4 degree off-cut 4H-SiC (0001) were found using scanning tunneling microscopy (STM). These nano-ridge…
Multilayer graphene, Moiré patterns, grain boundaries and defects identified by scanning tunneling microscopy on the m-plane, non-polar surface of SiC
P. Xu, D. Qi, J. K. Schoelz +9
Epitaxial graphene is grown on a non-polar n+ 6H-SiC m-plane substrate and studied using atomic scale scanning tunneling microscopy. Multilayer graphene is found throughout the sur…
Towards pristine graphene-metal interface and microstructures: Laser assisted direct patterning on Epitaxial graphene
A. Nath, M. Currie, V. D. Wheeler +11
Graphene-metal contact resistance is governed by both intrinsic and extrinsic factors. Intrinsically, both the density of states bottleneck near the Dirac point and carrier reflect…
Membrane amplitude and triaxial stress in twisted bilayer graphene deciphered using first-principles directed elasticity theory and scanning tunneling microscopy
M. Neek-Amal, P. Xu, D. Qi +7
Twisted graphene layers produce a moiré pattern (MP) structure with a predetermined wavelength for given twist angle. However, predicting the membrane corrugation amplitude for any…
