Ja. Stroscio et al., HOMOEPITAXIAL GROWTH OF IRON AND A REAL-SPACE VIEW OF REFLECTION-HIGH-ENERGY-ELECTRON DIFFRACTION, Physical review letters, 70(23), 1993, pp. 3615-3618
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 ra
nge of 20-250-degrees-C. The effect of the diffusion kinetics is obser
ved in the surface morphology as a decrease in the interface width wit
h temperature. Measurements of reflection-high-energy-electron diffrac
tion during growth allow a comparison of real and reciprocal space tec
hniques.
