Abstract
An electron beam is deflected when it passes over a silicon nitride surface, if the surface is illuminated by a low-power continuous-wave diode laser. A deflection angle of up-to is achieved for an electron beam of divergence. A mechanical beam-stop is used to demonstrate that the effect can act as an optical electron switch with a rise and fall time of . Such a switch provides an alternative means to control electron beams, which may be useful in electron lithography and microscopy.
