TEMPLATED GROWTH AND PROPERTIES OF IRON NANOWIRES: ANISOTROPIC ELECTRON STATES OF THE QUASI 1D COPPER SUBSTRATE, AND MORPHOLOGICAL AND MAGNETIC PROPERTIES OF THE IRON ADSORBATE.

Abstract

Templated growth and properties of iron nanowires: anisotropic electron states of the quasi 1D copper substrate, and morphological and magnetic properties of the iron adsorbate. PhD Student: Carlos Eduardo Viol Barbosa Advisor: Giorgio Rossi, Alberto Morgante. Low dimensional and nano-scale material systems display quantum behavior due to the confinement in one or more dimensions of the electron states. The goal of nanoscience is to understand and exploit such behavior. Reaching such goal implies growing or fabricating nano-scale systems with atomic precision, not achievable by statistical top down methods. Self-organized and self-assembled systems on single crystal surfaces are prototypical atomically precise systems since they can be reduced to 1 (quantum wire) or 0 (quantum dot) dimension, maintaining the atomic precision of crystal. The surface reconstruction of stepped surfaces, induced by locally selective chemical reactions, is exploited in the present work to produce: a) a quasi 1D stripes array of single crystal terraces that can be studied both by local probes to establish the morphology and the local density of states as well as by means of extended electronic structure technique
