Short Description

The project is aimed to provide the student the basic knowledge of Density Functional Theory (DFT) and Non Equilibrium Green's Function (NEGF) method. They represent the state-of-art of modelling for numerical simulations in vibrational, optical, and electronic properties and transport properties of functional devices, respectively. To obtain accurate results and predict the characteristics of not-yet-fabricated structures, DFT and NEGF must be combined with each other. The project will focus on the study of electro-thermal properties of devices whose active region is a van der Waals material, where two Transition Metal Dichalcogenides monolayers are stacked on top of each other only in their central part.

The Big Picture

Integrated electronics constitute one of the most important and spread aspects of our everyday life and among the years the size shrinking of transistors, the active component of all integrated circuits, has been supported and encouraged by several aspects. Nevertheless, the indefinitely reduction of dimensions cannot be the only prospective, but it must be combined with the research of new channel materials and geometries able to replace Silicon. Due to their ultimate thickness, van der Waals inter-layer coupling, intra-layer covalent bonds and surface free of dangling bonds, artificial van der Waals materials are expected to exhibit unique features
