Plain silicon grating reveals a hidden 'twist' in light from electron beams
Physicists have discovered that when an electron beam passes near a plain silicon grating, the color of the emitted light is determined by two specific factors. This phenomenon was first observed in 1953 and has since been used to create compact light sources and track particle beams. The discovery could lead to further innovations in these areas.
