Electromechanics in graphene

How and why does the resistance of a graphene nanostructure change, when placed in a pressure cell?


Researchers of the BME Quantum Electronics group, along with colleagues at ETH Zürich, address this question in their recent experiment. Two bilayer graphene flakes are pushed against each other in a twisted fashion, akin to recent breakthrough experiments discovering superconductivity in similar samples. The team measured the resistance of the nanostructure as function of pressure and temperature; this allowed to infer key features of the electronic band structure as well. The results are publised in Nano Letters.
