Confined Monolayer Ag as a Large Gap 2D Semiconductor

Shih, MacDonald, Li (UT MRSEC); Crespi, Robinson (Penn State MRSEC)
By mapping momentum-resolved electronic states using time-resolved and angle-resolved photoemission spectroscopy, researchers recently revealed that monolayer Ag confined between bilayer graphene and SiC is a large gap (>1 eV) 2D semiconductor, consistent with ab initio GW calculations.

Ferroelectric Superconductivity in a Transition Metal Dichalcogenide

A. Saha, T. Birol, R. Fernandes (IRG-1)
For the first time, a team comprised of two IRG-1 theorists (Birol  and Fernandes) working with experimentalists from other institutions (including  the  Columbia  MRSEC) showed the  coexistence of ferroelectricity (i.e.,  electrostatically switchable macroscopic dipole moment) and superconductivity in a two-dimensional superconductor.

Inverse Design of Mechanical Metamaterials with Target Nonlinear Response via a Neural Accelerated Evolution Strategy

Katia Bertoldi (Mechanics) and Chris Rycroft (Applied Math)
A team at the Harvard MRSEC led by Bertoldi and Rycroft  has  developed  a  framework  to  design mechanical  metamaterials  with  target  nonlinear response. Neural networks were used to accurately learn  the  relationship  between  the  geometry  and nonlinear   mechanical   response   of   these metamaterials.
