Epitaxial Ferroelectric Hexagonal Boron Nitride Grown on Graphene

Advanced Materials, EarlyView.
The epitaxial growth of hexagonal boron nitride (h‐BN) multilayer films on graphene, synthesized on a miscut SiC (0001) substrate, is demonstrated using nitrogen plasma‐assisted molecular‐beam epitaxy. Robust ferroelectricity with switchable out‐of‐plane polarization via interlayer sliding is supported by theoretical and experimental insights ...

Inflation, symmetry, and B-modes

Physics Letters B, 2015
We examine the role of using symmetry and effective field theory in inflationary model building. We describe the standard formulation of starting with an approximate shift symmetry for a scalar field, and then introducing corrections systematically in ...

Deep Learning Analysis of Localized Interlayer Stacking Displacement and Dynamics in Bilayer Phosphorene

Advanced Materials, EarlyView.
Interlayer displacement plays a crucial role in tuning properties of layered crystals, yet its precise and efficient determination remains challenging. A deep learning‐based analysis is presented for atomic‐resolution phase‐contrast transmission electron microscopy (TEM) images, accurately identifying stacking displacement in bilayer phosphorene with ...
