Resumen:

In this chapter, we review the electronic properties of several two-dimensional (2D) material families, including multilayered systems. Several 2D materials are covered: graphene, silicene and other group-IV elements, phosphorene, transition metals dichalcogenides, and monochalcogenide-monolayers. An emphasis is given on the similarities and differences between families. We start by providing a short crystallographic and diffraction description, showing its importance as a general framework to understand the main features of charge-carrier propagation. Then we examine the theoretical tools needed to model the electronic properties, including Dirac and Weyl materials. A discussion is also presented concerning the importance of free-electron bands to describe interactions between graphene with substrates and polar liquids as water. Such tools allow one to describe a new playground for observing exotic matter phases, such as Kekulé patterns, moiré patterns, graphene over graphene at magic angles, mixed Dirac-Schrödinger electronic spectrum, and topological insulator states. © 2020 Elsevier Ltd All rights reserved.
