2019 Project Proposal

Ultrafast laser science at the nanoscale

Brian Daly (Physics)

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 (a nanometer is one billionth of a meter). 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 have a collaboration with the Materials Science department at Penn State University to create and study thin films that are only one-atom thick!  Finally, we are also embarking on a computational modeling study of the interaction of light waves and vibrational waves in nanostructures.  Four positions are available; one or two students will have the opportunity to work at the 2D Crystal Consortium Materials Innovation Platform, a NSF national user facility https://www.mri.psu.edu/mip.

Prerequisites:
One year of physics and mathematics is required.  PHYS 200, 202/203 and MATH 220, 228 are recommended.

How should students express interest in this project?
Aside from this application, you do not need to contact me in order to express your interest in the project.  I will send out emails to contact you once I have read through all the applications.
