We report real space views of the homoepitaxial growth of Fe on Fe(001) whiskers observed by scanning tunneling microscopy. A measure of the surface diffusion of the Fe atoms is obtained over the temperature range of 20–250 °C. The effect of the diffusion kinetics is observed in the surface morphology as a decrease in the interface width with temperature. Measurements of reflection-high-energy-electron diffraction during growth allow a comparison of real and reciprocal space techniques.

  11. Here we are assuming only single atoms are mobile on the surface (single atoms are not seen in the STM images), and are taking the island capture numbers to be unity. Previous analyses have shown that taking the capture numbers to be unity would not change the functional dependence on temperature (or the derived activation energy), but can affect the overall magnitudes of the diffu\%sion coefficients through a multiplicative factor by less than a factor of 10 [8,9].
