Broadband Optical Detection using the Spin Seebeck Effect
Subash Kattel, Joseph R. Murphy, David Ellsworth +5
The generation, control, and detection of spin currents in solid-state devices are critical for Joule-heating minimization, spin-based computation, and electrical energy generation…
Global alignment of solution-based single-wall carbon nanotube films via machine-vision controlled filtration
Joshua S. Walker, Jeffrey A. Fagan, Adam J. Biacchi +4
Over the past decade, substantial progress has been made in the chemical processing (chiral enrichment, length sorting, handedness selectivity, and filling substance) of single-wal…
Direct Measurements of Magnetic Polarons in CdMnSe Nanocrystals from Resonant Photoluminescence
W. D. Rice, W. Liu, V. Pinchetti +3
In semiconductors, quantum confinement can greatly enhance the interaction between band carriers (electrons and holes) and dopant atoms. One manifestation of this enhancement is th…
Revealing Optically Induced Magnetization in SrTiO using Optically Coupled SQUID Magnetometry and Magnetic Circular Dichroism
W. D. Rice, P. Ambwani, J. D. Thompson +2
In this work, we study the time- and temperature-dependence of optically induced magnetization in bulk crystals of slightly oxygen-deficient SrTiO using an optically couple…
Observation of Coulomb-Assisted Dipole-Forbidden Intraexciton Transitions in Semiconductors
W. D. Rice, J. Kono, S. Zybell +14
We use terahertz pulses to induce resonant transitions between the eigenstates of optically generated exciton populations in a high-quality semiconductor quantum-well sample. Monit…
Enhancement of the Electron Spin Resonance of Single-Walled Carbon Nanotubes by Oxygen Removal
W. D. Rice, R. T. Weber, A. D. Leonard +6
We have observed a nearly fourfold increase in the electron spin resonance (ESR) signal from an ensemble of single-walled carbon nanotubes (SWCNTs) due to oxygen desorption. By per…
Spin Relaxation Times of Single-Wall Carbon Nanotubes
W. D. Rice, R. T. Weber, P. Nikolaev +4
We have measured temperature ()- and power-dependent electron spin resonance in bulk single-wall carbon nanotubes to determine both the spin-lattice and spin-spin relaxation tim…
Resonant Raman Spectroscopy of Armchair Carbon Nanotubes: Absence of "Metallic" Signature
E. H. Haroz, J. G. Duque, W. D. Rice +3
The appearance of a broad peak at 1550 cm (G peak) in carbon nanotube resonant Raman scattering spectra has been conventionally attributed to the presence of met…
Carbon Nanotube Terahertz Polarizer
L. Ren, C. L. Pint, L. G. Booshehri +8
We describe a film of highly-aligned single-walled carbon nanotubes that acts as an excellent terahertz linear polarizer. There is virtually no attenuation (strong absorption) when…
