Krispy Kreme Challenge
- Present 8 years 3 months
The Krispy Kreme Challenge is a student-led, charity-based race founded at NC State University in 2004. Participants run from the campus bell tower to the Krispy Kreme store, eat a dozen doughnuts, and run back. In 2004, I won the inaugural race and in 2005 served as a race director. The annual event draws over 5000 participants each year, and has raised over $1,350,000 for the North Carolina Children's Hospitals. The event has received national press attention, including a feature on ESPN…

dysprosium-doped cadmium oxide as a gateway material for mid-infrared plasmonics.

See publicationthe interest in plasmonic technologies surrounds many emergent optoelectronic applications, such as plasmon lasers, transistors, sensors and information storage. although plasmonic materials for ultraviolet-visible and near-infrared wavelengths have been found, the mid-infrared range remains a challenge to address: few known systems can achieve subwavelength optical confinement with low loss in this range. with a combination of experiments and ab initio modelling, here we demonstrate an extreme…
the interest in plasmonic technologies surrounds many emergent optoelectronic applications, such as plasmon lasers, transistors, sensors and information storage. although plasmonic materials for ultraviolet-visible and near-infrared wavelengths have been found, the mid-infrared range remains a challenge to address: few known systems can achieve subwavelength optical confinement with low loss in this range. with a combination of experiments and ab initio modelling, here we demonstrate an extreme peak of electron mobility in dy-doped cdo that is achieved through accurate 'defect equilibrium engineering'. in so doing, we create a tunable plasmon host that satisfies the criteria for mid-infrared spectrum plasmonics, and overcomes the losses seen in conventional plasmonic materials. in particular, extrinsic doping pins the cdo fermi level above the conduction band minimum and it increases the formation energy of native oxygen vacancies, thus reducing their populations by several orders of magnitude. the substitutional lattice strain induced by dy doping is sufficiently small, allowing mobility values around 500 cm(2) v(-1) s(-1) for carrier densities above 10(20) cm(-3). our work shows that cdo:dy is a model system for intrinsic and extrinsic manipulation of defects affecting electrical, optical and thermal properties, that oxide conductors are ideal candidates for plasmonic devices and that the defect engineering approach for property optimization is generally applicable to other conducting metal oxides.

Surfactant-enabled epitaxy through control of growth mode with chemical boundary conditions
Nature Communications
See publicationOur collaborative study of the surfaces of CaO show that an otherwise unfavorable polar growth mode can be stabilized under appropriate growth conditions. This growth control will allow smooth, layer-by-layer growth in polar orientations.
