Silicon-Silicide nanocomposite heterostructures for Silicon based photonics, opto- and thermoelectronics

Tuesday, 06.05.2014 13:00 - 13:30

Prof. Nikolay Galkin (Institute of Automation and Control Processes of FEB RAS, 5 Radio Str., 690041, Vladivostok, Russia)

In presented report short review of nanocomposite structure formation based on embedded nanocrystallites of semiconductor silicides of Fe, Cr, Mg, Mn, Ca in the monocrystalline and poycrystalline silicon in silicon and their electrical and optical properties have been presented. It was shown that b-FeSi2 and CrSi2 NCs with sizes (5-20 nm) have a strained crystal structure with lattice constants on 1.0 – 2.5% smaller than those for the bulk silicides.

Fabrication and characterization of selected carbon-based nano-structures

Tuesday, 06.05.2014 13:30 - 14:00

Oleg Babchenko (Institute of Physics ASCR)

The presentation will be devoted to the results of the research work that includes:

  • Investigation of the different nucleation strategies influence on diamond thin film growth using the microwave plasma assisted chemical vapour deposition (CVD) technique. In addition, study on the selective area diamond structures deposition, as related to previous;
  • Continuous and porous poly- and nano-crystalline diamond films growth in the two different types of deposition equipment.

Non-adiabatic molecular dynamics with electron transitions

Tuesday, 06.05.2014 15:00

Vladimír Zobač (Department of Thin Films and Nanostructures, FZÚ AV ČR, v.v.i.)

Abstract: Non-adiabatic molecular dynamics provides an important tool for the study of photochemical reactions, which has potential application in many fields. Non-adiabatic molecular dynamics is rapidly developing field of research and various non-adiabatic methods based on quantum or classical trajectories were developed. One of the most commonly used method is trajectory surface hopping method, which offer an interesting compromise between accuracy and efficiency for the simulation of large-scales molecular systems.

A STM approach to molecular conductance and the properties of ZnO

Tuesday, 06.05.2014 15:00 - 16:00

Richard Berndt (Institut für Experimentelle und Angewandte Physik, Christian-Albrechts-Universität zu Kiel, Germany)

The electron transport through single molecules and atoms as well as molecule--molecule contacts is investigated with low-temperature scanning probe microscopy. In the experiments, which aim at maximizing the control over the junction properties, the conductance, the acting forces and the emission of photons are probed. The talk will initially address the role of molecular structure and bonding as well as quantum noise properties. In a second part, I will present some recent results on the structure of the ZnO(0001) surface and the spectroscopy of subsurface donors.

Physics behind 100J/10Hz laser for new scientific applications

Wednesday, 21.05.2014 15:00

Antonio Lucianetti (Institute of Physics ASCR)

High-energy-class diode-pumped solid-state lasers are being developed worldwide for new scientific and industrial applications, including particle acceleration, intense X-ray generation and inertial confinement fusion. Traditional efforts to scale the output energy of solid-state lasers have led to undesirable beam-quality degradation.
