Diamond Surface Functionalization via Visible Light-Driven C-H Activation for Nanoscale Quantum Sensing
Lila V. H. Rodgers, Suong T. Nguyen, James H. Cox +16
Nitrogen-vacancy centers in diamond are a promising platform for nanoscale nuclear magnetic resonance sensing. Despite significant progress towards using NV centers to detect and l…
Resonant soft X-ray scattering reveals hierarchical structure in a multi-component vapor-deposited glass
Camille Bishop, Thomas J. Ferron, Marie E. Fiori +5
Multi-phase vapor-deposited glasses are an important class of materials for organic electronics, particularly organic photovoltaics and thermoelectrics. These blends are frequently…
A Structural Phase Transition in Ca3Co4O9 Associated with Enhanced High Temperature Thermoelectric Properties
Tao Wu, Trevor A. Tyson, Haiyan Chen +3
Temperature dependent electrical resistivity, crystal structure and heat capacity measurements reveal a resistivity drop and metal to semiconductor transition corresponding to firs…
Polar State in Freestanding Strontium Titanate Nanoparticles
Trevor A. Tyson, Tian Yu, Mark Croft +6
Monodispersed strontium titanate nanoparticles were prepared and studied in detail. It is found that ~10 nm as-prepared stoichiometric nanoparticles are in a polar structural state…
Understanding The Reversible Electrodeposition of Al in Low-Cost Room Temperature Molten Salts
Regina Garcia-Mendez, Jingxu Zheng, David C. Bock +6
Aluminum is the most earth-abundant metal, is trivalent, is inert in ambient humid air, and has a density approximately four-times that of lithium at room temperature. These attrib…
Molecular beam growth of graphene nanocrystals on dielectric substrates
Ulrich Wurstbauer, Theanne Schiros, Cherno Jaye +9
We demonstrate the growth of graphene nanocrystals by molecular beam methods that employ a solid carbon source, and that can be used on a diverse class of large area dielectric sub…
Characterization of Silicon-Membrane TES Microcalorimeters for Large-Format X-ray Spectrometers with Integrated Microwave SQUID Readout
Avirup Roy, Robinjeet Singh, Joel C. Weber +17
We present the electro-thermal characterization of transition-edge sensor (TES) detectors suspended on Si membranes fabricated using a silicon-on-insulator (SOI) wafer. The use of…
Low-Loss Superconducting Resonators Fabricated from Tantalum Films Grown at Room Temperature
Guillaume Marcaud, David Perello, Cliff Chen +16
The use of -tantalum in superconducting circuits has enabled a considerable improvement of the coherence time of transmon qubits. The standard approach to grow -tantalum th…
Origins of diamond surface noise probed by correlating single spin measurements with surface spectroscopy
Sorawis Sangtawesin, Bo L. Dwyer, Srikanth Srinivasan +15
The nitrogen vacancy (NV) center in diamond exhibits spin-dependent fluorescence and long spin coherence times under ambient conditions, enabling applications in quantum informatio…
