Molecular Geometry Determination by Atomic Force Microscopy

Seminar / Tue, 07/10/2014 - 10:00 - 11:00

Nikolaj Moll (IBM Research Zurich, Ruschlikon, Switzerland)

Using functionalized tips, the atomic resolution of a single organic molecule can be achieved by atomic force microscopy (AFM) operating in the regime of short-ranged repulsive Pauli forces while the van der Waals and electrostatic interactions only add a diffuse attractive background. To theoretically describe the atomic contrast a simple model is introduced in which the Pauli repulsion is assumed to follow a power law as a function of the probed charge density. Even, different bond orders of individual carbon-carbon bonds in organic molecules can be distinguished by AFM.

Diamond Field Effect Transistors with high-k gate insulator

Seminar / Thu, 09/10/2014 - 10:00 - 11:00

Yasuo Koide (Network and Facilities Services Division; Wide Bandgap Materials Group, Optical and Electronic Materials Unit, National Institute for Materials Science (NIMS), Japan)

Diamond has an attractive interest as one of next-generation power electronics materials. Since the sheet hole density in the hydrogenated-diamond surface was reported to be as high as 1E14 cm-2 which was one or two orders larger than other semiconductors. Therefore, we should use such the big advantage and then have to develop the high-k gate dielectric for diamond in order to control the high-density hole carrier.

International Workshop on Relaxor Ferroelectrics

Conference / Sun, 12/10/2014 - Thu, 16/10/2014

We are proud to host the first regular International Workshop on Relaxor Ferroelectrics in Stirin, Czech Republic, on 12–16 October 2014. The Workshop will will initiate a biannual worldwide discussion forum focused on the physics and applications of relaxor ferroelectrics, their structure, polar nanoregions, nanodomains, dielectric and piezoelectric properties, relation to structural and spin glasses, spectroscopic data etc.

For more information, please visit the Workshop website at http://palata.fzu.cz/iwrf14/.
