Abstract
The sputtering of an amorphous solid is considered analytically and the equations of motion of the changing surface topography derived.
These equations are solved to show that a steady state is reached only in conditions where the surface topography consists of planes aligned, either parallel or perpendicular to the direction of sputtering ion incidence.
