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…
Long Phonon Mean Free Paths Observed in Cross-plane Thermal-Conductivity Measurements of Exfoliated Hexagonal Boron Nitride
Gabriel R. Jaffe, Keenan J. Smith, Kenji Watanabe +4
Sub-micron-thick layers of hexagonal boron nitride (hBN) exhibit high in-plane thermal conductivity, useful optical properties, and serve as dielectric encapsulation layers with lo…
Three-Omega Thermal-Conductivity Measurements with Curved Heater Geometries
Gabriel R. Jaffe, Keenan J. Smith, Victor W. Brar +2
The three-omega method, a powerful technique to measure the thermal conductivity of nanometer-thick films and the interfaces between them, has historically employed straight conduc…
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…
