Ferroelectric Properties of van der Waals Chalcogenides: DFT perspective
Xue Li, James G. McHugh, Vladimir I. Falko
Layered materials with non-centrosymmetric stacking order are attracting increasing interest due to the presence of ferroelectric polarization, which is dictated by weak interlayer…
Competition of moiré network sites to form electronic quantum dots in reconstructed MoX/WX heterostructures
Isaac Soltero, Mikhail A. Kaliteevski, James G. McHugh +2
Twisted bilayers of two-dimensional semiconductors offer a versatile platform to engineer quantum states for charge carriers using moiré superlattice effects. Among the systems of…
Twirling and spontaneous symmetry breaking of domain wall networks in lattice-reconstructed heterostructures of 2D materials
M. A. Kaliteevsky, V. V. Enaldiev, V. I. Fal'ko
Lattice relaxation in twistronic bilayers with close lattice parameters and almost perfect crystallographic alignment of the layers results in the transformation of moiré pattern i…
Mixing of surface and bulk electronic states at a graphite-hexagonal boron nitride interface
Ciaran Mullan, Sergey Slizovskiy, Jun Yin +12
Van der Waals assembly enables exquisite design of electronic states in two-dimensional (2D) materials, often by superimposing a long-wavelength periodic potential on a crystal lat…
Flat bands for electrons in rhombohedral graphene multilayers with a twin boundary
Aitor Garcia-Ruiz, Sergey Slizovskiy, Vladimir I. Fal'ko
Topologically protected flat surface bands make thin films of rhombohedral graphite an appealing platform for searching for strongly correlated states of 2D electrons. In this work…
Umklapp electron-electron scattering in bilayer graphene moiré superlattice
Christian Moulsdale, Vladimir Fal'ko
Recent experimental advances have been marked by the observations of ballistic electron transport in moiré superlattices in highly aligned heterostructures of graphene and hexagona…
