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-…
Self-referencing photothermal common-path interferometry to measure absorption of Si3N4 membranes for laser-light sails
Tanuj Kumar, Demeng Feng, Shenwei Yin +12
Laser-light sails are a spacecraft concept wherein lightweight "sails" are propelled by high-intensity lasers. We investigated the near-infrared absorption of free-standing membran…
Electrostatic Steering of Thermal Emission with Active Metasurface Control of Delocalized Modes
Joel Siegel, Shinho Kim, Margaret Fortman +6
We theoretically describe and experimentally demonstrate a graphene-integrated metasurface structure that enables electrically-tunable directional control of thermal emission. This…
The Effect of Dust and Hotspots on the Thermal Stability of Laser Sails
Gabriel R. Jaffe, Gregory R. Holdman, Min Seok Jang +3
Laser sails propelled by gigawatt-scale ground-based laser arrays have the potential to reach relativistic speeds, traversing the solar system in hours and reaching nearby stars in…
