Surface studies of the Fe/Mo(110) and Fe/W(100) epitaxial systems

THESIS 6127This thesis describes the investigation of ultrathin Fe film growth on the Mo(110) and W(100) surfaces, using scanning tunneling microscopy (STM), low-energy electron diffraction (LEED) and Auger electron spec?troscopy (AES). A general review of the current understanding of epitaxial film growth is given, covering both thermodynamic and kinetic aspects of theory. The experimental set-up and conditions under which the Fe/Mo(110) and Fe/W(100) epitaxial systems were studied are described. This includes a description of the preparation procedure for novel STM tips of MnNi, Fe and Cr, that were used in the study
