Research Objectives and Results
-Implement electrically detected electron-nuclear double resonance (ENDOR); acquire preliminary data.
- -Develop a state-of-the-art user facility for high-field (12 Tesla) electron and nuclear spin manipulation.
- -Optimize and scale a recently demonstrated, newly invented organic magnetometer device based on a spintronic effect; find optimal material for this device.
- -Perform analytical calculation of the influence of exchange, hyperfine, and spin-orbit coupling on spin-coherently controlled electric current and optical emission.
-Perform numerical simulation of the influence of dipolar coupling on spin-coherently controlled electric current and optical emission.
- -Demonstrate low-field optically detected magnetic resonance in conjugated polymers.
- -Characterize nuclear spin relaxation in organic semiconductors, as a limit to polarization transfer from the hyperfine interaction.
- -Multifrequency pulse EPR (Bruker Elxsys E580) spectrometer with ENDOR and ELDOR (electron-electron double resonance) insert, with two self-built low frequency pulsed EDMR/ODMR spectrometers.
- -Multifrequency two-channel (Tecmag Redstone) NMR spectrometer.
-Standard sample preparation glove-box facility.
-Photolithography, deposition, and fabrication of inorganic device components through the University of Utah’s Nanofabrication Facility.
- -A unique self-contained facility to carry out low-temperature single-molecule spectroscopy that is particularly suited for the investigation of systems with a high degree of intramolecular disorder — such as conjugated polymers.
