Fractional AC Josephson effect in a topological insulator proximitized by a self-formed superconductor
Ilan T. Rosen, Christie J. Trimble, Molly P. Andersen +10
A lateral Josephson junction in which the surface of a 3D topological insulator serves as the weak link should support topologically protected excitations related to Majorana fermi…
A high-mobility electronic system at an electrolyte-gated oxide surface
Patrick Gallagher, Menyoung Lee, Trevor A. Petach +5
Electrolyte gating is a powerful technique for accumulating large carrier densities in surface two-dimensional electron systems (2DES). Yet this approach suffers from significant s…
Quantum oscillations from a two-dimensional electron gas at a Mott/band insulator interface
Pouya Moetakef, Daniel G. Ouellette, James R. Williams +4
We report on the magnetotransport properties of a prototype Mott insulator/band insulator perovskite heterojunction in magnetic fields up to 31 T and at temperatures between 360 mK…
Carrier-controlled ferromagnetism in SrTiO3
Pouya Moetakef, James R. Williams, Daniel G. Ouellette +4
Magnetotransport and superconducting properties are investigated for uniformly La-doped SrTiO3 films and GdTiO3/SrTiO3 heterostructures, respectively. GdTiO3/SrTiO3 interfaces exhi…
Etching of Graphene Devices with a Helium Ion Beam
M. C. Lemme, D. C. Bell, J. R. Williams +4
We report on the etching of graphene devices with a helium ion beam, including in situ electrical measurement during lithography. The etching process can be used to nanostructure a…
Quantum Hall Effect in a Graphene p-n Junction
J. R. Williams, L. DiCarlo, C. M. Marcus
We report on the fabrication and transport studies of a single-layer graphene p-n junction. Carrier type and density in two adjacent regions are individually controlled by electros…
