Probing Topological Surface States and Conduction via Extended Defects in (BiSb)Te Films
Abby Liu, Armando Gil, Moon-ki Choi +10
(BiSb)Te alloys are non-degenerate topological insulators (TIs) whose Dirac point (DP) can be tuned within the bulk bandgap by varying the composition, effectiv…
Interatomic potential development for topological insulator Bi1-xSbx and its dislocation by force-following active learning
Moon-ki Choi, Daniel Palmer, Harley T. Johnson
We introduce a force following active learning algorithm that integrates density functional theory DFT with the Gaussian Approximation Potential GAP framework to develop a robust i…
Graph Neural Network for Unified Electronic and Interatomic Potentials: Strain-tunable Electronic Structures in 2D Materials
Moon-ki Choi, Daniel Palmer, Harley T. Johnson
We introduce UEIPNet, an equivariant graph neural network designed to predict both interatomic potentials and tight-binding (TB) Hamiltonians for an atomic structure. The UEIPNet i…
Quantifying superlubricity of bilayer graphene from the mobility of interface dislocations
Md Tusher Ahmed, Moon-ki Choi, Harley T Johnson +1
Van der Waals (vdW) heterostructures subjected to interlayer twists or heterostrains demonstrate structural superlubricity, leading to their potential use as superlubricants in mic…
