Transport phenomena in nanowires, nanotubes, and other low-dimensional systems

Seminář / Úterý, 14.03.2017 10:00 - 11:00

First principles calculations have been implemented to study the ground state and electron transport properties of nanoscale materials and to evaluate its performance in electronic devices (magnetic tunneling junctions, field effect transistors and gas sensors). The ground state properties are studied within density functional theory using the SIESTA code, whereas the transport properties are investigated using the non-equilibrium Green’s functions formalism implemented in the SMEAGOL code.

Endohedral metallofullerenes: in cavea redox reactions and single molecule magnetism

Seminář / Středa, 15.03.2017 15:00 - 16:00

Fullerenes encapsulating metal atoms in their interior are known as endohedral metallofullerenes (EMFs). Since the first discovery of EMFs in the gas phase in 1985 and development of their arc-discharge synthesis in early 1990s, the field of EMFs showed dramatic advancement. Carbon cage shields endohedral species from environment and thus stabilizes different types of metal clusters, which cannot exist by themselves. Exotic valence and spin states can be realized for such clusters.

Epitaxial Graphene on SiC

Seminář / Úterý, 28.03.2017 10:00 - 11:00

Ten years ago, ground-breaking experimental studies of graphene – a monolayer of carbon with honeycomb structure – were reported. Charge carriers in graphene are described by the Weyl-Hamiltonian for massless particles, resulting in interesting properties such as an unusual quantum Hall effect or Klein tunneling which sparked the interest of scientists around the world. They are characterized by a high mobility, which makes graphene interesting for electronic applications such as high frequency transistors and frequency mixers.

Helical Molecules and Surfaces: Self-Assembly, Spin Filtering and Unidirectional Motors

Seminář / Čtvrtek, 06.04.2017 15:00 - 16:00

The Nobel Prize for Chemistry 2016 is shared by Jean-Pierre Sauvage, J. Fraser Stoddard and Ben Feringa for the development of molecular machines. The three researchers designed molecules with subunits that moved relative to each other in a controlled manner, and therefore founded a new field in chemistry. Some of their molecules can, for example under influence of light, even fulfill work. The three laid the foundation for nanoscopic motors, like molecular escalators, molecular muscles and nanocars.
