Imaging topological polar structures in marginally twisted 2D semiconductors
Thi-Hai-Yen Vu, Daniel Bennett, Gayani Nadeera Pallewella +16
Moire superlattices formed in van der Waals heterostructures due to twisting, lattice mismatch and strain present an opportunity for creating novel metamaterials with unique proper…
Visualization of Strain-Induced Landau Levels in a Graphene - Black Phosphorus Heterostructure
Thi-Hai-Yen Vu, Pin Lyu, Na Hyun Jo +8
Strain-induced pseudo magnetic fields offer the possibility of realizing zero magnetic field Quantum Hall effect in graphene, possibly up to room temperature, representing a promis…
Observation of charge density wave excitonic order parameter in topological insulator monolayer WTe2
Liam Watson, Joan Ripoll, Zhengjue Tong +12
Strong electron-hole interactions in a semimetal or narrow-gap semiconductor may drive a ground state of condensed excitons. Monolayer WTe2 has been proposed as a host material for…
Three-dimensional flat band in ultra-thin Kagome metal Mn3Sn film
Mengting Zhao, James Blyth, Grace L. Causer +12
Flat bands with small energy dispersion can give rise to strongly correlated electronic and topological phases, especially when located at the Fermi level. Whilst flat bands have b…
