In order to clarify the structures of thin Cr films by their real space ima
ges, Cr films of various thicknesses, prepared using vacuum deposition, hav
e 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 delta-Cr. The well-known bcc chromium particles
were observed in thick and large crystal particles. The stability of small
particles is discussed. (C) 2000 Published by Elsevier Science S.A. All rig
