Abstract

Ti films of 10 nm thickness prepared by evaporation onto NaCl substrates at 250°C have been studied by high-resolution electron microscopy. The films have two characteristic regions: CaF2-type TiHx crystallites predominated, while h.c.p. Ti crystallites containing (1(formula presented)01) and/or ((formula presented)011) twin boundaries grew in the other region. This is the first observation of (1(formula presented)01) twins in evaporated h.c.p. Ti films. Furthermore, misfit dislocations and a gentle bending of the TiHx lattice occurred at the interface between TiHx and h.c.p. Ti, owing to lattice mismatch strains. The orientation relationships and growth mechanism of the epitaxial films, especially of the h.c.p. Ti films, is discussed.
