Mind the Gap -- Imaging Buried Interfaces in Twisted Oxide Moirés

Harikrishnan KP, Xin Wei, Chia-Hao Lee +10

The ability to tune electronic structure in twisted stacks of two-dimensional (2D) materials has motivated the exploration of similar moiré physics with twisted oxide membranes. Du…

Bright hybrid excitons in molecularly tunable bilayer crystals

Tomojit Chowdhury, Aurélie Champagne, Patrick Knüppel +8

Bilayer crystals, built by stacking crystalline monolayers, generate interlayer potentials that govern excitonic phenomena but are constrained by fixed covalent lattices and orient…
