Winding Berry dipole on uniaxially strained graphene/hBN/hBN moiré trilayers
Angiolo Huaman, Salvador Barraza-Lopez
Nonlinear Hall-like currents can be generated by a time-periodic alternating bias on two-dimensional (2D) materials lacking inversion symmetry. To hint that the moiré between graph…
Creating a three dimensional intrinsic electric dipole on rotated CrI bilayers
Shiva P. Poudel, Juan M. Marmolejo-Tejada, Joseph E. Roll +2
Two-dimensional (2D) materials are being explored as a novel multiferroic platform. One of the most studied magnetoelectric multiferroic 2D materials are antiferromagnetically-coup…
Two-atom-thin topological crystalline insulators lacking out of plane inversion symmetry
Salvador Barraza-Lopez, Gerardo G. Naumis
A two-dimensional topological crystalline insulator (TCI) with a single unit cell (u.c.) thickness is demonstrated here. To that end, one first shows that tetragonal ( in-plan…
Beyond Graphene: Low-Symmetry and Anisotropic 2D Materials
Salvador Barraza-Lopez, Fengnian Xia, Wenjuan Zhu +1
Low-symmetry 2D materials---such as ReS and ReSe monolayers, black phosphorus monolayers, group-IV monochalcogenide monolayers, borophene, among others---have more complex…
Colloquium: Physical properties of group-IV monochalcogenide monolayers
Salvador Barraza-Lopez, Benjamin M. Fregoso, John W. Villanova +2
We survey the state-of-the-art knowledge of ferroelectric and ferroelastic group-IV monochalcogenide monolayers. These semiconductors feature remarkable structural and mechanical p…
Tuning energy barriers by doping 2D group-IV monochalcogenides
Albert Du, Zachary Pendergrast, Salvador Barraza-Lopez
Structural degeneracies underpin the ferroic behavior of next-generation two-dimensional materials, and lead to peculiar two-dimensional structural transformations under external f…
