Chemical sensing by graphene field effect transistors

Úterý, 04.03.2014 10:00 - 11:00

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.

Magnetic properties of single molecules and metal-organic networks on surfaces

Úterý, 04.03.2014 13:00 - 14:00

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.

Calculating ultrafast magnetization dynamics

Úterý, 04.03.2014 15:00

Karel Carva (Oddělení teoretické fyziky, katedry fyziky kondenzovaných látek, MFF UK)

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.

The role of electrochemistry in semiconductor growth and degradation

Čtvrtek, 06.03.2014 10:00 - 11:00

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).
