Post-doctoral Researchers

Modelling two-dimensional-based gas sensors


Research area or group: Theoretical and Computational Nanoscience Group

Description of Group/Project: The host develops cutting-edge theoretical research on quantum transport phenomena in graphene and 2D materials and has a long experience in large-scale simulations of complex materials. In-house methodologies allow the simulation of disordered materials containing up to hundred millions atoms, enabling predictive modelling and collaboration with experimental and technology research. The group has been funded by company such as SAMSUNG, and is member of the Graphene Flagship project since 2014.

The project is connected to an EU-FET project in which European industries and engineering laboratories will develop novel generation of gas sensors, while the group will be in charge of the modelling tasks to guide the experimental towards optimisation of devices and support the interpretation of measurements.

Main Tasks and responsibilities:

The candidate will conduct numerical simulations of the optical and electrical conductivity of graphene under CO2 or water adsorption.  These simulations will assess the impact of unwanted surface contamination on the electrical output signals. Calculation of the variations of electrical and thermal conductivities of a "heated graphene patch" will be performed using molecular dynamics and time-evolution Kubo transport methods to deduce a relative change with respect to the reference situation (absence of CO2 or water). Comparison with experimental data will be achieved to extract the intrinsic signals from parasitic ones and access the upper sensitivity limit of the detector structures.

Education, Experience, Knowledge and Competences required:

Theoretical physics and quantum simulations (molecular dynamics DFT and/or tight-binding modelling), and experience in device simulation or simulation of photodetectors would be a plus. Fluent in English.
