Beyond Graphene: Advanced 2D Electronic and Optoelectronic Crystals and Devices for Next Generation Applications
Abstract
The discovery of graphene, made of an individual atomic-thick layer of carbon, could be considered as a defining point in the research and development of stable truly 2D material systems. This breakthrough has opened up the possibility of isolating and exploring the fascinating properties of atomic layers of other layered materials in the form of MeX2 (where Me = transition metal such as Mo, W, Ti, Nb, etc. and X = S, Se, or Te), and hexagonal boron nitride (hBN), which upon reduction to single/few atomic layers, will offer functional flexibility, new physico-chemical properties and novel applications. Each of these material systems exhibit specific properties that complement the technological goals of many applications, including field effect transistors, photodetectors, chemical and biological sensors, and nanoelectromechanical systems. However, there are multiple, well defined challenges to synthesis of electronic-grade layered materials, heterogeneous integration of these films, development of devices that utilize the unique properties of these materials.
