Ultrafast optical studies of nanoscale material properties*
Brian Daly (Physics and Astronomy)
Ultrafast lasers produce pulses of light that are less than 1 picosecond (A millionth of a millionth of a second) in duration. These remarkable light sources allow for investigations of extremely short lived phenomena in solid materials. Of particular interest to my research group are the conduction of heat and the propagation of ultrasound in novel nanostructures. We have several goals this summer. First, we have an ongoing project to study surface acoustic waves at their highest possible frequencies-near 50 GHz. Second, we are beginning a study of novel materials that are grown in single or few atom thick layers such as graphene and transition metal dichalcongenides. Techniques will include laser experiments, the growth of thin metal films, and computational modeling of vibrational and electromagnetic waves.
Prerequisites: Completion of PHYS 113/114 by the end of the spring semester is required. Completion of PHYS 200/202/203 by the end of spring semester is recommended.
How should students express their interest in this project? I will not be able to contact every student who applies to my program. I will contact you directly if I need to follow up with any additional questions.
