Abstract
Diffusion of titanium adsorbed on the (013) region of tungsten single microcrystal was investigated using the field emission current fluctuation method. The measurements were carried out for titanium layers chosen from the range about 0.2–2 monolayers in the temperature range 300–1500K. The autocorrelation function of the field emission current fluctuation was used to determine the diffusion coefficients and activation energy for surface diffusion of the adsorbate. A temperature range of 950–1450K was found where thermally activated diffusion occurred. The values of the activation energy depend on coverage and they change in the range of 0.84–1.13eV.
