Fig.2. Measurement of electric currents induced by the electric field of light. The proof-of-principle study was performed on a small silica-glass prism, coated on two sides with gold electrodes with a 50nm gap in between. In order to investigate the field-induced electric current the scientists exposed the sample to the strong few-cycle field of a pulse for "mobilizing" electrons and then drove the mobilized electrons towards one of the two electrodes with the field of a time-delayed second (weaker) laser pulse.
