Electronic properties and adsorption behaviour of thin films with polar character
N. Nilius, Fritz-Haber-Institut der MPG, Germany
Thin films of polar nature are distinctively different from their non-polar counterparts. They feature characteristic properties in their surface morphology, electronic structure and adsorption behaviour, which originate from the effort of such systems to lower the polarity-induced electrostatic energy. This chapter provides insight into the general concepts of polarity and typical polarity healing mechanisms. A main focus is the polarity of thin oxide films and the chapter deals with the various observable consequences of uncompensated surface dipoles in such systems. Furthermore, the distinct ...
