Interaction of magnetic and non-magnetic metals with graphene

Tuesday, 14.04.2015 15:00

Hendrik Vita (Department of Physical Chemistry, Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin)

Abstract: The investigation of the electronic properties of graphene-metal interfaces is of great current interest, not only from a fundamental point of view, but also with respect to possible applications in electronic devices and other fields. The (111) surface of iridium is used as a template for graphene growth, in view of the weak interaction between the partners, and due to the excellent structural quality. The used experimental method is photoemission and –absorption.

Surface engineering in silicon- and germanium- based nanocrystals

Tuesday, 21.04.2015 10:00 - 11:00

Alexander Poddubny (Ioffe Physical-Technical, 26 Politekhnicheskaya st., St. Petersburg 194021, Russia)

The two possibilities to control and enhance the optical properties of the nanocrystals made from indirect band-gap semiconductors are presented by quantum confinement and surface engineering. The quantum confinement effect can lead to the relaxation of the momentum conservation rules for small nanocrystal sizes while the surface engineering offers the possibility to manipulate the eigenstates of confined carriers in the reciprocal space due to the valley mixing effects.
