Photocurrent control in nanoscale systems offers opportunities for nanoelectronic devices and ultrafast imaging applications. Here, the authors show by means of angle-resolved two-dimensional velocity mapping that angular photoemission distributions can be controlled by varying the polarization and frequency of the laser.
