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…
Thermal mirror buckling in freestanding graphene locally controlled by scanning tunneling microscopy
M. Neek-Amal, P. Xu, J. K. Schoelz +5
Knowledge of and control over the curvature of ripples in freestanding graphene are desirable for fabricating and designing flexible electronic devices, and recent progress in thes…
Unusual ultralow frequency fluctuations in freestanding graphene
P. Xu, M. Neek-Amal, S. D. Barber +5
Intrinsic ripples in freestanding graphene have been exceedingly difficult to study. Individual ripple geometry was recently imaged using scanning tunneling microscopy, but these m…
Self-Organized Platinum Nanoparticles on Freestanding Graphene
Peng Xu, Lifeng Dong, Mehdi Neek-Amal +8
Freestanding graphene membranes were successfully functionalized with platinum nanoparticles (Pt NPs). High-resolution transmission electron microscopy revealed a homogeneous distr…
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…
