Surfaces & Interfaces


To gain atomic-level controll over material structure and composition it is necessary to understand the basic processes taking place during relevant steps of preparation of nanostuctured surfaces. One of goals of our research is to steer the self ordering processes taking place on surfaces. Under well defined ultra-high vacuum conditions we study nucleation of islands and thin films, surface diffusion, diffusion of metal atoms through thin films employing various techniques of surface analysis like XPS, LEED, SEM, AFM, and STM. 

Recently, we have started experimental studies of self-assembly processes form organic and metal components on metallic (Au, Ag, Cu) and graphene surfaces and study their catalytic properties on molecular level using scanning tunelling microscopy, XPS and LEEM. Ph.D. positions open! List of bachelor thesis topics (in Czech).

 Cechal Jan 190410 0020AMy research is focused on understanding of the fundamental phenomena taking during nucleation and growth of thin films (clusters, islands), self-assembly complex metal-organic nanostructures at surfaces, and revealing the possibilities to steer these processes. My other research interests comprise the morphological and chemical analysis using X-ray photoelectron spectroscopy (XPS or ESCA) and synthesis of graphene using chemical vapor deposition (CVD). I have received Ph.D. on applied physics at Brno University of Technology (Czech Republic) exploring the possibilities of morphological analysis by XPS. In 2010 I joined the group of prof. Klaus Kern at Max-Planck Institute for Solid State Research in Stuttgart (Germany) under individual Marie Curie fellowship studying surface confined molecular systems. In 2012 I became a researcher at CEITEC in Brno, Czech Republic developing the research on self-assembly of molecular nanostructures at surface.

One dimensional semiconducting materials (whiskers, nanowires, nanotubes) are nowadays intensively studied for their predicted superior functional properties, being quite different from bulk materials. Our research is focused on investigation of different nanowire growth modes and their engineering toward unconventional geometries (different cross-sections and sidewall orientations, nanowire junctions formation etc.). We utilize evaporation from the solid source (Ge, Si,Zn,Ga,Sb) which allows for real-time in-situ observation of nanowire formation and growth in scanning electron microscope. Our group has a strong link to FEI company, seated in Brno.

The images taken by SEM show germanium nanowires (70-200 nm in diameter) and their growh process as observed in real time. For most of the growth experiments, we utilize a liquid catalyst droplet (visible on nanoire top). The understanding of the droplet behavior in the initial stages and during growth is a key for further engineering nanowire structures towards desired shape and morphology. The real time SEM experiments revealed a plethora of previously unknown phenomena, and confirmed modelling predictions as well.

1d331c8n My research interest is in materials science at micro- and nanoscale. I am currently focusing on physical phenomena causing growth of 1D semiconductor and metal oxide nanostructures (nanowires, rods, whiskers…) which have promising electronic and optical properties for applications in nanoelectronics and biosensing. Other research interests include wet and dry passivation techniques of semiconductor surfaces and guided growth of metallic nanostructures. My background is in solid state physics and surface science. I have received PhD from Brno University of Technology, with thesis topic Low Energy Ion Spectroscopy. I am tutoring several undergraduate and graduate students. I have several topics for bachelor, diploma or PhD thesis open - you are welcome to contact me.
