What is Time-Resolved Electron Microscopy?

Electron microscopy (EM) is a powerful imaging technique renowned for its outstanding spatial resolution. It surpasses the theoretical maximum resolving power of conventional microscopy by several orders of magnitude. This enables researchers to probe nanoscale structures and to resolve the chemical composition of samples with unprecedented precision. However, standard EM systems are typically unsuited to … Continue reading

Unraveling Ultrafast Hot Electron Dynamics

Hot electron relaxation and transport in nanostructures involves a multitude of ultrafast processes relevant for applications in photocatalysis and optoelectronics. Researchers from Lund University employ time-resolved photoemission electron microscopy (Tr-PEEM) to image the relaxation of photogenerated hot electrons within InAs nanowires on a femtosecond time scale. According to Prof. Donatas Zigmantas, “High repetition rate of PHAROS is … Continue reading
