Mission
The photo-emission electron microscope (PEEM) is capable of imaging nanoscale surface structures (~20 nm) via electron emission induced by ultraviolet and laser light sources. The PEEM is applied to surface science studies of individual nanostructures and tailored plasmonic constructs. Experiments can be performed with either static or dynamic light sources. In particular, femtosecond laser excitation allows pump-probe studies of surface plasmon propagation revealing the underlying physics required to turn nanoscale structures into miniaturized nanophotonic circuits.
