Seed IV: Suspended Graphene Devices for Quantum Electronics and Nanosensing @ Massachusetts Institute of Technology
Pablo Jarillo-Herrero, Assistant Professor, Department of Physics
The research objective of this seed project is to investigate electronic transport in ultra-high mobility suspended graphene devices (GDs) both to study fundamental quantum electronics and to assess their potential as chemical and mass nanosensors.
A crucial element of this research is the fabrication of high-quality suspended GDs. Multiterminal devices (see Figure below) will be used to study fundamental quantum phenomena, such as the fractional quantum Hall effect or the spin Hall effect, while high quality suspended GNRs will be actuated as tunable high-frequency nanoresonators. In addition, the possibility of passivating the edges of GNRs with desired chemical groups will enable ultra-sensitive chemical and mass detection.
