2D materials and van der Waals heterostructures
K. S. Novoselov, A. Mishchenko, A. Carvalho +1
The physics of two-dimensional (2D) materials and heterostructures based on such crystals has been developing extremely fast. With new 2D materials, truly 2D physics has started to…
Polarization and valley switching in monolayer group-IV monochalcogenides
Paul Z. Hanakata, Alexandra Carvalho, David K. Campbell +1
Group-IV monochalcogenides are a family of two-dimensional puckered materials with an orthorhombic structure that is comprised of polar layers. In this article, we use first princi…
Multiferroic Two-Dimensional Materials
L. Seixas, A. S. Rodin, A. Carvalho +1
The relation between unusual Mexican-hat band dispersion, ferromagnetism and ferroelasticity is investigated using a combination of analytical, first-principles and phenomenologica…
