Two-dimensional disorder in black phosphorus and monochalcogenide monolayers
Mehrshad Mehboudi, Alex M. Dorio, Wenjuan Zhu +6
Ridged, orthorhombic two-dimensional atomic crystals with a bulk {\em Pnma} structure such as black phosphorus and monochalcogenide monolayers are an exciting and novel material pl…
Preserving the 7x7 surface reconstruction of clean Si(111) by graphene adsorption
Justin C. Koepke, Joshua D. Wood, Cedric M. Horvath +2
We employ room-temperature ultrahigh vacuum scanning tunneling microscopy (UHV STM) and {\em ab-initio} calculations to study graphene flakes that were adsorbed onto the Si(111)…
Intrinsic defects, fluctuations of the local shape, and the photo-oxidation of black phosphorus
Kainen L. Utt, Pablo Rivero, Mehrshad Mehboudi +4
Black phosphorus is a monoatomic semiconducting layered material that degrades exothermically in the presence of light and ambient contaminants. Its degradation dynamics remain lar…
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…
