Knudsen Cell

The Miniature K-cell provides the ideal tool for reproducibly depositing small area thin films of material, with coverages ranging from sub-monolayer to continuous films. The material to be deposited is heated to provide a suitable vapour pressure in an isothermal enclosure. Molecular effusion from an aperture in the end of the cell gives rise to a cosine intensity distribution. The deposition rate is extremely stable, being determined by the temperature of the enclosure which is accurately controlled using a thermocouple and temperature Controller.
