Abstract
We apply a new formalism to calculating emission of light from sheared dielectric surfaces. When the surfaces are smooth, the emission of light requires extreme velocities, but introducing surface roughness with short-period components reduces the extreme demands on velocity so that, for atomic-scale roughness, shear velocities as small as 104 ms−1 will result in light emission. Some order-of-magnitude estimates are given.Keywords
