Nano-Acoustic Material Spectroscopy:

Dispersion signature of acoustic phonons carries detailed information about the physical properties of solids. We develop nano-acoustic test-vehicles to extract physical and material information at the nano-scale, where conventional optical / electron microscopy & spectroscopy techniques fail to provide sufficient resolution.  Tabrizian lab explores the application of nano-acoustic spectroscopy to extract morphological information and quantify crystal phase transitions in atomic-layer ferroelectric films, where XRD fails to provide sufficient resolution.
