The structure of thin Cr film prepared by the vacuum evaporation method

In order to clarify the structures of thin Cr films by their real space images, Cr films of various thicknesses, prepared using vacuum deposition, have been observed using a high resolution electron microscope. The amorphous chromium films were composed of microcrystallites of the order of 3 nm. The crystallite structure was δ-Cr. The well-known bcc chromium particles were observed in thick and large crystal particles. The stability of small particles is discussed.
