Organometallic Hexahapto Functionalization of Single Layer Graphene as a Route to High Mobility Graphene Devices
Santanu Sarkar, Hang Zhang, Jhao-Wun Huang +4
Organometallic hexahapto chromium metal complexation of single layer graphene, which involves constructive rehybridization of the graphene pi-system with the vacant chromium d orbi…
Transport in Suspended Monolayer and Bilayer Graphene Under Strain: A New Platform for Material Studies
Hang Zhang, Jhao-Wun Huang, Jairo Velasco +9
We develop two types of graphene devices based on nanoelectromechanical systems (NEMS), that allows transport measurement in the presence of in situ strain modulation. Different mo…
Visualizing Electrical Breakdown and ON/OFF States in Electrically Switchable Suspended Graphene Break Junctions
Hang Zhang, Wenzhong Bao, Zeng Zhao +8
Narrow gaps are formed in suspended single to few layer graphene devices using a pulsed electrical breakdown technique. The conductance of the resulting devices can be programmed b…
Aryl Functionalization as a Route to Band Gap Engineering in Single Layer Graphene Devices
Hang Zhang, Elena Bekyarova, Jhao-Wun Huang +5
Chemical functionalization is a promising route to band gap engineering of graphene. We chemically grafted nitrophenyl groups onto exfoliated single-layer graphene sheets in the fo…
