Abstract

The growth and structure of Ti films evaporated on ultra-high-vacuum- and air-cleaved NaCl substrates at room temperature have been studied by reflection high-energy electron diffraction. The 2 nm-thick film on the former showed bcc- and CaF2-type (TiH1.5) reflections while that on the latter showed TiH1.5ones immediately after the evaporation. Judging from the lattice parameter (0.33 nm), the bcc crystallite was analyzed to be β-Ti. This is the first observation of β-Ti grown in evaporated Ti films. The β-Ti changed into TiH1.5with time. This spontaneous hydrogenation mechanism of the evaporated Ti films is discussed.
