Characterization of hexagonal boron nitride layers on nickel surfaces by low-energy electron microscopy
P. C. Mende, Q. Gao, A. Ismach +5
The thickness and interfacial geometry of hexagonal boron nitride (hBN) films grown by chemical vapor deposition on polycrystalline nickel foils is studied using low-energy electro…
Inelastic Effects in Low-Energy Electron Reflectivity of Two-dimensional Materials
Qin Gao, P. C. Mende, M. Widom +1
A simple method is proposed for inclusion of inelastic effects (electron absorption) in computations of low-energy electron reflectivity (LEER) spectra. The theoretical spectra are…
Phase Transitions of Boron Carbide: Pair Interaction Model of High Carbon Limit
Sanxi Yao, W. P. Huhn, M. Widom
Boron Carbide exhibits a broad composition range, implying a degree of intrinsic substitutional disorder. While the observed phase has rhombohedral symmetry (space group R3(bar)m),…
First Principles Study of Bismuth Films at Transition Metal Grain Boundaries
Qin Gao, Michael Widom
Recent experiments suggest that Bi impurities segregate to form bilayer films on Ni and Cu grain boundaries but do not segregate in Fe. To explain these phenomena, we study the tot…
Shapes and textures of ferromagnetic liquid droplets
S. Banerjee, M. Widom
Theoretical calculations, computer simulations and experiments indicate the possible existence of a ferromagnetic liquid state. Should such a state exist, demagnetization effects w…
Total-energy-based prediction of a quasicrystal structure
M. Mihalkovič, I. Al-Lehyani, E. Cockayne +5
Quasicrystals are metal alloys whose noncrystallographic symmetry and lack of structural periodicity challenge methods of experimental structure determination. Here we employ quant…
