Abstrakt: We describe a low-energy electron diffraction process with a periodical modulation of the electron beam intensity. The conditions to get a coherent modulated beam are investigated, first, by simulating the electron trajectories and second, by analyzing the diffraction pattern oscillation. The large increase in the dynamic range is exemplified by diffraction of the electrons by mica surface nanostructures. [ABSTRACT FROM AUTHOR]
