	Description:		It is demonstrated that surface-sensitive electron diffraction measurements of steps on singular, but rough Si(100) surfaces are subject to a multiple-scattering effect that can be misinterpreted as double-atomic-height steps. It is shown that only single-height steps are present. This phenomenon can occur in any surface in which adjacent terraces have different terrace structure factors. Determination of terrace sizes can be influenced; however, they can be accurately made if the diffraction geometry is chosen appropriately. Possible terrace shape effects may also be inherent in the diffraction data.
