Simulated scanning tunneling microscopy images of few-layer-phosphorus capped by graphene and hexagonal boron nitride monolayers
Pablo Rivero, Cedric M. Horvath, Zhen Zhu +3
Elemental phosphorous is believed to have several stable allotropes that are energetically nearly degenerate, but chemically reactive. To prevent chemical degradation under ambient…
Stability and properties of high-buckled two-dimensional tin and lead
Pablo Rivero, Jia-An Yan, Victor M. Garcia-Suarez +2
In realizing practical non-trivial topological electronic phases stable structures need to be determined first. Tin and lead do stabilize an optimal two-dimensional high-buckled ph…
Polar catastrophe in ultra-thin limit: A case of rare-earth perovskite LaNiO3
S. Middey, P. Rivero, D. Meyers +6
We address the fundamental issue of growth of perovskite ultra-thin films under the condition of a strong polar mismatch at the heterointerface exemplified by the growth of a corre…
Graphene's morphology and electronic properties from discrete differential geometry
Alejandro A. Pacheco Sanjuan, Zhengfei Wang, Hamed Pour Imani +2
The geometry of two-dimensional crystalline membranes dictates their mechanical, electronic and chemical properties. The local geometry of a surface is determined from the two inva…
Quantitative Chemistry and the Discrete Geometry of Conformal Atom-Thin Crystals
Alejandro A. Pacheco Sanjuan, Mehrshad Mehboudi, Edmund O. Harriss +2
When flat or on a firm mechanical substrate, the atomic composition and atomistic structure of two-dimensional crystals dictate their chemical, electronic, optical, and mechanical…
