Frank Hegmann, PhD
My expertise is in ultrafast phenomena of materials, terahertz (THz) science and technology, ultrafast scanning tunneling microscopy (STM), optics and photonics, and nanophysics. I have two labs in Physics, the Ultrafast Spectroscopy Lab and the Ultrafast Nanotools Lab, where we use advanced femtosecond laser sources to perform time-resolved THz spectroscopy and THz-STM for exploring fundamental ultrafast processes in materials down to the atomic scale.
