Abstract

A micromechanical light valve, using metallic coatings on a flexible dielectric material and an electrostatic deflection mechanism initiated by electron beam addressing, can have its performance enhanced by overcoating the metal with a high secondary electron-emitting material, such as MgO.

Electron Emissive Coating for Structured Target Light Valve

A micromechanical light valve, using metallic coatings on a flexible dielectric material and an electrostatic deflection mechanism initiated by electron beam addressing, can have its performance enhanced by overcoating the metal with a high secondary electron-emitting material, such as MgO.

The potential benefits are in the areas of writing speed, beam current and resolution.
