Real-Space Imaging of Photogenerated Carrier Dynamics via 4D Scanning Ultrafast Electron Microscopy

This project investigates the spatial and temporal evolution of photogenerated charge carriers in gallium arsenide (GaAs) and cadmium telluride (CdTe) using 4D Scanning Ultrafast Electron Microscopy (4D-SUEM). The acquired time-resolved images are processed and quantitatively analyzed using intensity profiles and two-component exponential fitting to characterize the photo-induced surface dynamics. The results reveal different photo-induced responses in GaAs and CdTe, providing insight into their surface carrier behavior and its relevance to photovoltaic and optoelectronic applications.
