Light-emittting silicon nanostructures [I. Pelant]

The laboratory works on electrochemical preparation of silicon nanocrystals (with sizes of several nanometers only) and on experimental investigation of their optical properties, in particular luminescence. Besides the basic problems connected with an understanding of relevant processes of radiative recombination in nanoparticles, an important motivation factor for this type of research lies in application potential of these nanoparticles for novel sources of optical radiation in the so called silicon nanophotonics.   The whole text »

Thin layers and nano-characterization [J. Kočka, A. Fejfar]

The laboratory main aim is PECVD preparation of nanostructures and thin layers based on silicon, in particular with micro-crystalline and nano-crystalline structures (μc-Si:H, nc-Si:H). For optimization of properties their complete characterization is necessary on both macroscropic and nano levels through combined measurements of AFM. The perspective use of these materials is mainly for photovoltaic conversion of solar energy.

Nanosurf [P. Jelínek, V. Cháb]

The main laboratory aim regarding the Nanosurf is a comprehensive research of atomic and electron structure of surfaces and nanostructures through experimental (STM/AFM, photoelectron spectroscopy, SPA-LEED) and theoretical methods (namely the computer simulation). The laboratory is concentrating not only on deeper understanding of physical processes leading to formation of nanostructures on the surface of solid substances but also on research and modification of their mechanical and electronic properties. These findings play an important role for design and optimization of new devices determined for nano-electronic.

Functional Nano-Interfaces [B. Rezek]

The laboratory of Functional Nano-Interfaces is working on fabrication and optimization of interfaces and nanostructures based on thin films of semiconducting materials (in particular silicon and diamond), organic molecules (e.g. organic dyes or DNA molecules) and human cells. Fundamental issue is merging those materials into hybrid nanosystems with the control of growth, orientation and position using physical and chemical parameters, and subsequently characterizing their functionality with respect to the target applications in electronics, optics, medicine, environment, security and other domains.
