Investigation of prototype devices in two-dimensional materials.

The exploration of novel low dimensional atomically thin materials is very important for a future generation of flexible nanoelectronics, optoelectronics, and energy storage devices. Among these, graphene has demonstrated a wide range of properties including, high electrical and thermal conductivity, and optical transparency. Due to the semiconducting nature of transition metal dichalcogenides, they are also becoming promising candidates. More recently, high frequency devices containing few layer black phosphorous have been demonstrated. Combining these materials in heterostructures would lead to a many-fold enhancement in their functionalities. In this proposal, with the combined effort of the two teams, prototype devices containing 2D heterostructures will be investigated. A deep understanding of the stability and electronic properties of heterostructures, investigated by the Chinese team with the use of ab-inito simulations will be coupled to effective models of prototype devices, either at tight binding or continuum level, led by the Belgian team. Systems comprised of vertical and in-plane heterostructures will be used to propose candidate devices taking advantage of either the charge or spin degrees of freedom. Of special interest are also tunable opto-electronic and excitonic effects. It is expected that this collaborative effort will lead to both a fundamental understanding of optoelectronic processes and the modeling of specific nano- and microelectronic devices.
