	Prof. Hongwen Jiang Fabricate and Characterize Semiconductor Quantum-dot Structures
	The REU student will join the postdocs and graduate students in the group to fabricate and characterize of semiconductor quantum-dot structures for developing of electron spin based quantum information processor.
	Prof. Gary Williams Luminescence Pulse
	This would be a project to study the luminescence pulse that is emitted from laser-induced bubbles in a variety of different liquids. The initial focused laser pulse ionizes a small volume of the liquid, and subsequently the energy deposited creates an expanding bubble filled with gas from the recombining atoms. The bubble reaches a maximum radius and then collapses, heating the gas to about 10,000 K at its minimum radius, giving off a nanosecond-scale pulse of light. The plan is to study this effect in organic liquids such as alcohol-water mixtures, and in viscoelastic gels. The time dependence of the luminescence pulse will be measured, and also the spectrum of the light (see our publications Physical Review Letters 83, 2437 (1999) and 86, 4934 (2001)).
