Abstract

The decrease in the dimensions of electronic and optoelectronic circuitry is directly linked to a potential increase in their speed of operation. On nanometer dimensions electrons typically move on attosecond to femtosecond timescales. The inherent link of these spatial and temporal dimensions and the promise of ultrafast light-driven nanocircuits have stimulated the development of the new field of attosecond nanophysics. An essential prerequisite for advancing this new field is the availability of methods that permit the characterization of light-stimulated electron dynamics and the resulting near-fields with highest temporal resolution.
