A scanning probe microscopy approach for identifying defects in aluminum oxide
Leah Tom, Zachary J. Krebs, Joel B. Varley +8
The coherence of quantum dot qubits fabricated in semiconductors is often limited by charge noise from defects in gate dielectrics, which are material- and process-dependent. Chara…
Implementing Josephson Junction spectroscopy in a scanning tunneling microscope
Margaret A. Fortman, David C. Harrison, Ramiro H. Rodriguez +6
Josephson junction spectroscopy is a powerful local microwave spectroscopy technique that has promising potential as a diagnostic tool to probe the microscopic origins of noise in…
Imaging the diffusive-to-ballistic crossover of magnetotransport in graphene
Zachary J. Krebs, Wyatt A. Behn, Keenan J. Smith +6
Scanning tunneling potentiometry (STP) is used to probe the local, current-induced electrochemical potential of carriers in graphene near circular electrostatic barriers in an out-…
Imaging the breaking of electrostatic dams in graphene for ballistic and viscous fluids
Zachary J. Krebs, Wyatt A. Behn, Songci Li +5
The flow of charge carriers in materials can, under some circumstances, mimic the flow of viscous fluids. In order to visualize the consequences of such effects, new methodologies…
Semi-adsorption-controlled growth window for half Heusler FeVSb epitaxial films
Estiaque H. Shourov, Ryan Jacobs, Wyatt A. Behn +8
The electronic, magnetic, thermoelectric, and topological properties of Heusler compounds (composition or ) are highly sensitive to stoichiometry and defects. Here we…
Dynamic Bandstructure and Capacitance Effects in Scanning Tunneling Spectroscopy of Bilayer Graphene
Gregory R. Holdman, Zachary J. Krebs, Wyatt A. Behn +4
We develop a fully self-consistent model to describe scanning tunneling spectroscopy (STS) measurements of Bernal-stacked bilayer graphene (BLG), and we compare the results of our…
Transient Structured Fluctuations in a Two-dimensional System with Multiple Ordered Phases
Ari B. Roitman, Linsey M. Nowack, Chris Liepold +2
We report the structure of transient fluctuations in the liquid phase of a two-dimensional system that exhibits several ordered phases with different symmetries. The density-temper…
