Ballistic miniband conduction in a graphene superlattice
Menyoung Lee, John R. Wallbank, Patrick Gallagher +4
Rational design of artificial lattices yields effects unavailable in simple solids, and vertical superlattices of multilayer semiconductors are already used in optical sensors and…
Robust fractional quantum Hall effect and composite fermions in the Landau level in bilayer graphene
Georgi Diankov, Chi-Te Liang, Francois Amet +9
The fractional quantum Hall (FQH) effect is a canonical example of electron-electron interactions producing new ground states in many-body systems. Most FQH studies have focused on…
Switchable friction enabled by nanoscale self-assembly on graphene
Patrick Gallagher, Menyoung Lee, Francois Amet +8
Graphene monolayers are known to display domains of anisotropic friction with twofold symmetry and anisotropy exceeding 200 percent. This anisotropy has been thought to originate f…
Universal Conductance Fluctuations in Electrolyte-Gated SrTiO3 Nanostructures
Sam W. Stanwyck, P. Gallagher, J. R. Williams +1
We report low-temperature magnetoconductance measurements of a patterned two-dimensional electron system (2DES) at the surface of strontium titanate, gated by an ionic liquid elect…
Disorder-induced gap behavior in graphene nanoribbons
Patrick Gallagher, Kathryn Todd, David Goldhaber-Gordon
We study the transport properties of graphene nanoribbons of standardized 30 nm width and varying lengths. We find that the extent of the gap observed in transport as a function of…
