Unraveling quantum Hall breakdown in bilayer graphene with scanning gate microscopy
M. R. Connolly, R. K. Puddy, D. Logoteta +7
We use low-temperature scanning gate microscopy (SGM) to investigate the breakdown of the quantum Hall regime in an exfoliated bilayer graphene flake. SGM images captured during br…

Reading and writing charge on graphene devices
M. R. Connolly, E. D. Herbschleb, R. K. Puddy +5
We use a combination of charge writing and scanning gate microscopy to map and modify the local charge neutrality point of graphene field-effect devices. We give a demonstration of…

Magnetic field induced confinement-deconfinement transition in graphene quantum dots
G. Giavaras, P. A. Maksym, M. Roy
Massless Dirac particles cannot be confined by an electrostatic potential. This is a problem for making graphene quantum dots but confinement can be achieved with a magnetic field…
