“…Using a gold photocathode driven by laser pulses and a streak camera for time-resolved detection, they revealed the correlation of local carrier dynamics in GaAs nanostructures with the surface morphology. In parallel with the developments in the laser-driven cathode, advances in ultrafast beam blankers promise a flexible and easily integrated method to generate electron pulses with a broad range of pulse widths and repetition rates, while keeping a good spatial resolution with a typical duration of tens of picoseconds. , In recent years, time-resolved CL with pulsed electron beams in SEM has enabled the dynamic study of exciton diffusion, ,, carrier relaxation, ,− and excited states of DNA . Currently, time-resolved CL studies performed in TEM have also been reported, , making progress toward elucidating structure–function relations at atomic scales.…”
