Chemical profiles of the oxides on tantalum in state of the art superconducting circuits
Russell A. McLellan, Aveek Dutta, Chenyu Zhou +23
Over the past decades, superconducting qubits have emerged as one of the leading hardware platforms for realizing a quantum processor. Consequently, researchers have made significa…
Visualizing Atomic-Scale Negative Differential Resistance in Bilayer Graphene
Keun Su Kim, Tae-Hwan Kim, Andrew L. Walter +4
We investigate the atomic-scale tunneling characteristics of bilayer graphene on silicon carbide using the scanning tunneling microscopy. The high-resolution tunneling spectroscopy…
Extraordinary epitaxial alignment of graphene islands on Au(111)
Joseph M. Wofford, Elena Starodub, Andrew L. Walter +7
Pristine, single-crystalline graphene displays a unique collection of remarkable electronic properties that arise from its two-dimensional, honeycomb structure. Using in-situ low-e…
Highly p-doped graphene obtained by fluorine intercalation
Andrew L. Walter, Ki-Joon Jeon, Aaron Bostwick +8
We present a method for decoupling epitaxial graphene grown on SiC(0001) by intercalation of a layer of fluorine at the interface. The fluorine atoms do not enter into a covalent b…
