Modeling of Electron Devices Based on 2-D Materials

In this paper we review the state of the art in simulation of electron devices based on two-dimensional materials. We outline the main methods to model the electronic bandstructure and to study electron transport, classifying them in terms of accuracy and computational cost. We briefly discuss how they can be combined in a multiscale approach to provide quantitative understanding of the mechanisms determining the operation of electron devices and we examine the application of these methods to the different families of 2D materials. Finally we shortly analyze the main open challenges of modeling 2D-based electron devices.
