Structure and magnetism of MnGe thin films grown with a nonmagnetic CrSi template
B. D. MacNeil, J. S. R. McCoombs, D. Kalliecharan +7
We report a method to grow B20 MnGe thin films using molecular-beam epitaxy, which employs an ultrathin CrSi template layer on Si(111). This layer is expected to be nonmagnetic, in…
Two-dimensional Indium Oxide at the Epitaxial Graphene/SiC Interface: Synthesis, Structure, Properties, and Devices
Furkan Turker, Bohan Xu, Chengye Dong +15
High-quality two-dimensional (2D) dielectrics are crucial for fabricating 2D/3D hybrid vertical electronic devices such as metal-oxide-semiconductor (MOS) based Schottky diodes and…
Grain-size dependence of plastic-brittle transgranular fracture
Jean-Michel Scherer, Mythreyi Ramesh, Blaise Bourdin +1
The role of grain size in determining fracture toughness in metals is incompletely understood with apparently contradictory experimental observations. We study this grain-size depe…
Efficiency of band edge optical transitions of 2D monolayer materials: A high-throughput computational study
A. F. Gómez-Bastidas, Karthik Sriram, A. C. Garcia-Castro +1
We performed high-throughput density functional theory calculations of optical matrix elements between band edges across a diverse set of non-magnetic two-dimensional monolayers wi…
Anomalous properties of spark plasma sintered boron nitride solids
Abhijit Biswas, Peter Serles, Gustavo A. Alvarez +22
Hexagonal boron nitride (h-BN) is a brittle ceramic with a layered structure, however, recent experiments have suggested that inter-layer structural engineering could be key to new…
Defect tolerance of lead-halide perovskite (100) surface relative to bulk: band bending, surface states, and characteristics of vacancies
Oleg Rubel, Xavier Rocquefelte
We characterized the formation of vacancies at a surface slab model and contrasted the results with the bulk of lead-halide perovskites using cubic and tetragonal CsPbI as repr…
