1. 1. Photoemission Electron Microscopy for Ultrafast Nano-Optics - Femtoseconds to Attoseconds

   Författare :Erik Mårsell; Synkrotronljusfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanorice; Spatiotemporal imaging; Attosecond pulses; Fysicumarkivet A:2016:Mårsell; Nanowires; Silver nanostructures; Femtosecond laser pulses; PEEM; Plasmonics; Ultrafast nano-optics;

   Sammanfattning : Ultrafast nano-optics is a new and quickly evolving research field centred around the control, manipulation, and application of light on a nanometre and femtosecond scale. This can lead to improved electro-optical devices, more sensitive spectroscopy, and real-time control of chemical reactions. LÄS MER

3. 2. Time-Resolved Photoemission Electron Microscopy: Development and Applications

   Författare :Lukas Wittenbecher; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEEM; time-resolved PEEM; ultrafast optics; pulse shaping; plasmonics; semiconductor nanowires; hot electrons; ultrafast microscopy; charge carrier relaxation;

   Sammanfattning : Time-resolved photoemission electron microscopy (TR-PEEM) belongs to a class of experimental techniquescombining the spatial resolution of electron-based microscopy with the time resolution of ultrafast opticalspectroscopy. This combination provides insight into fundamental processes on the nanometer spatial andfemto/picosecond time scale, such as charge carrier transport in semiconductors or collective excitations ofconduction band electrons at metal surfaces.
