Graphene Mass Sensor and Nanoribbon

Final Year Research Project for BEng in Aerospace Engineering

Single layer graphene sheet (SLGS) is investigated for its out-of-plane bending properties when subjected to a distributed or point force over different aspect ratios. Simulations of vibrations of graphene nanoribbons (GNR) are carried out to determine their pass-stop bands for different edges and aspect ratios.

A novel material

Graphene is a relatively novel material, discovered by physicists in 2004 at the University of Manchester. Its peculiar properties, most notably its unparalleled ability to transport electrons, prompted a research gold rush, with new research papers published regularly.

This research project uses a hybrid atomistic continuum finite element approach to model graphene. This hybrid approach benefits from the advantages of being computationally efficient from traditional continuum modeling and retaining the accuracy of atomistic models as sizes approach atomic scales.
