In recent years, the ability to synthesize, engineer & observe materials on the nanometer length scale has led to novel phenomena and applications. On the other hand, modern lasers deliver powerful, ultra short pulses of light allowing us to observe the interaction of electrons and atoms on the femtosecond timescale. Together, these technologies allow us to study new paradigms in light-matter interaction – with femtosecond temporal resolution and nanometer spatial resolution. In the Femtosecond Spectroscopy Unit, we direct these abilities towards four main research thrusts:
- 2D Materials and Heterostructures, where we search for new functionality and physics in two-dimensional materials and their heterostructures;
- Terahertz Applications and Devices, where artificially nano-engineered devices generate and manipulate low energy electromagnetic radiation;
- Energy Materials, where the ultrafast dynamics of photoexcited electrons and holes influence the ability to harness solar energy; and
- Techniques for Neuroscience & Drug Delivery, where femtosecond pulses trigger nanoscale devices to interface with neural functioning.
