Defective graphene as promising anode material for Na-ion battery and Ca-ion battery
Dibakar Datta, Junwen Li, Vivek B. Shenoy
We have investigated adsorption of Na and Ca on graphene with divacancy (DV) and Stone-Wales (SW) defect. Our results show that adsorption is not possible on pristine graphene. How…
The Equilibrium Shape of Graphene Domains on Ni(111)
Meifang Li, J. B. Hannon, R. M. Tromp +4
We have determined the equilibrium shape of graphene domains grown on Ni(111) via carbon segregation at 925°C. In situ, spatially-resolved electron diffraction measurements were us…
Bonding Charge Density and Ultimate Strength of Monolayer Transition Metal Dichalcogenides
Junwen Li, Nikhil V. Medhekar, Vivek B. Shenoy
Two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) can withstand a large deformation without fracture or inelastic relaxation, making them attractive for a…
