Discrete differential geometry and the properties of conformal two-dimensional materials
Salvador Barraza-Lopez
Two-dimensional materials were first isolated no longer than ten years ago, and a comprehensive understanding of their properties under non-planar shapes is still being developed.…
Strain and the optoelectronic properties of non-planar phosphorene monolayers
Mehrshad Mehboudi, Kainen Utt, Humberto Terrones +3
Lattice {\em Kirigami}, ultra-light metamaterials, poly-disperse aggregates, ceramic nano-lattices, and two-dimensional (2-D) atomic materials share an inherent structural discrete…
Strain-tunable topological quantum phase transition in buckled honeycomb lattices
Jia-An Yan, Mack A. Dela Cruz, Salvador Barraza-Lopez +1
Low-buckled silicene is a prototypical quantum spin Hall insulator with the topological quantum phase transition controlled by an out-of-plane electric field. We show that this fie…
Giant Surface Charge Density of Graphene Resolved From Scanning Tunneling Microscopy and First-Principles Theory
P. Xu, Y. Yang, S. D. Barber +6
In this work, systematic constant-bias, variable-current scanning tunneling microscopy (STM) measurements and STM simulations from density-functional theory are made, yielding crit…
Atomic Control of Strain in Freestanding Graphene
P. Xu, Y. Yang, S. D. Barber +8
In this study, we describe a new experimental approach based on constant-current scanning tunneling spectroscopy to controllably and reversibly pull freestanding graphene membranes…
A Pathway between Bernal and Rhombohedral Stacked Graphene Layers with Scanning Tunneling Microscopy
P. Xu, Y. Yang, D. Qi +7
Horizontal shifts in the top layer of highly oriented pyrolytic graphite, induced by a scanning tunneling microscope (STM) tip, are presented. Excellent agreement is found between…
