Jiří Červenka (School of Physics, The University of Melbourne)

Graphene's two dimensional nature, highly sensitive unique electrical properties and low intrinsic noise characteristics make it a prime candidate for the creation of a new generation of molecular sensors. Despite of high sensitivity of graphene sensors, their selectivity remains a major problem for their practical use. In this talk I present different strategies for selective sensing using graphene-based sensors.

Katharina J. Franke (Freie Universität Berlin)

The magnetic properties of atoms and molecules on a surface are significantly affected by details in the atomic-scale surrounding. Manipulation of this surrounding provides the possibility to tune the electronic and magnetic functionality of surfaces on a nanometer scale. Using scanning tunnelling spectroscopy (STS), we show that the lifetime of excited spin states in the paramagnetic Fe-Octaethylporphyrin-Chloride (FeOEP-Cl) is orders of magnitude longer when the molecule is adsorbed on a superconductor as compared to a normal metal substrate.

Abstract: In recent years it has been demonstrated that magnetization can be changed without applying an external magnetic field in extremely short timescales of the order of hundreds of femtoseconds [1]. We have studied the effect by means of ab initio calculations for three ferromagnetic metals Fe, Co and Ni [2] considering the Elliott-Yafet electron-phonon spin-flip (SF) scattering [3] which has been suggested to be the dominant microscopic mechanism.

Kristin Poduska (Department of Physics and Physical Oceanography Memorial University of Newfoundland, Canada)

Electrochemical methods are widely applied to metal film deposition in industrial and high-tech settings, but the market share for semiconductor films produced using electrochemistry is dramatically less. At the same time, a large fraction of semiconductor-based devices rely on applied voltages for their operation, which means that electrochemical processes could occur in these devices wherever there exists an interface between an electron conductor (such as a semiconductor) and an ion conductor (such as water).
