FIG. 1.

AS-t curves constructed from Fe growth on an as-received substrate and from growth on an -cleaned and annealed substrate. The substrate signal is tracked by following the evolution of the Auger peak from magnesium at (circles). The adsorbate signal is tracked by following the evolution of the Auger peak from iron at (squares). The filled symbols represent data from a film grown on an -cleaned and annealed substrate. The empty symbols represent data from a film grown on an as-received substrate. Dashed lines are fits to the data from growth on an as-received substrate. Solid lines are fits to the data from growth on an -cleaned and annealed substrate.

LEED diffraction patterns from a MgO(001) substrate (a) and Fe(001) films [(b) and (c)], all taken at . The samples in (a) and (b) are similarly positioned with respect to the electron beam, and the Fe lattice rotation relative to the MgO substrate is evident. Both Fe films are annealed to for and cooled to room temperature before performing LEED. Fe films grown on as-received substrates (b) produce less sharp diffraction spots than films grown on -cleaned and annealed substrates (c).

In-plane rotation XRD analysis of the Fe thin films. The of the signal intensities are plotted as a function of rotational angle . The solid line is from a MgO(001) substrate. The dotted line represents data from an iron film grown in an UHV system on an -cleaned and annealed substrate.
