Imaging nanoscale photocarrier traps in solar water-splitting catalysts
Levi D. Palmer, Wonseok Lee, Pushp Raj Prasad +12
Defects trap photocarriers and hinder solar water splitting. The nanoscale photocarrier transport, trapping, and recombination mechanisms are usually inferred from ensemble-average…
Imaging Nanoscale Carrier, Thermal, and Structural Dynamics with Time-Resolved and Ultrafast Electron Energy-Loss Spectroscopy
Wonseok Lee, Levi D. Palmer, Thomas E. Gage +1
Time-resolved and ultrafast electron energy-loss spectroscopy (EELS) is an emerging technique for measuring photoexcited carriers, lattice dynamics, and near-fields across femtosec…
Resonant Self-Diffraction of Femtosecond Extreme Ultraviolet Pulses in Cobalt
Alexei A. Maznev, Wonseok Lee, Scott K. Cushing +14
Self-diffraction is a non-collinear four-wave mixing technique well-known in optics. We explore self-diffraction in the extreme ultraviolet (EUV) range, taking advantage of intense…
The role of effective mass and long-range interactions in the band-gap renormalization of photo-excited semiconductors
Cian C. Reeves, Scott K. Cushing, Vojtech Vlcek
Understanding how to control changes in electronic structure and related dynamical renormalizations by external driving fields is the key for understanding ultrafast spectroscopy a…
