Hot Lasers, Fast Particles,
and Snapshots of Quantum Cats

Associate Professor of Chemistry
WU Outstanding Professor of 2010

Moderated by: Cynthia Wichelman, M.D.

Since the first LASER demonstration 50 years ago this month, improvements in the technology have enabled chemical reaction dynamics and molecular properties to be characterized with incredible temporal, spatial and energy resolution. Much of this work is intimately tied to the field of Quantum Mechanics, which is typically used to describe the behavior of nanoscopic (1-100 nanometer) or smaller particles and systems. We are currently using single-molecule optical microscopy methods to investigate the photophysics within single semiconductor quantum wires. These quantum wires—with diameters as small as 3.5 nm but lengths of up to 100 microns (105 nanometers)—nevertheless exhibit quantum mechanical phenomena that span their entire length. The results could significantly impact future solar cell designs.

Science On Tap highlighted on St. Louis Public Radio and Voice of America!

Science On Tap is a place where, for the price of a beverage, anyone can come to explore the latest ideas in science and technology. Meetings take place outside a traditional academic context, in the Crown Room at Schlafly Bottleworks.

Meetings are held on the last Wednesday of the month during the academic year, usually from 7:00 - 8:30 PM. The standard format is as follows: 20 minutes of presentation, followed by a 7 minute break for attendees to introduce themselves to each other at the table, and then an hour of discussion. Seating is limited to the first 100 people.  No reservations accepted.
