FIB SIMS is a modern physical tool for the creation of nanometer sized objects using a focused ion beam. Those nanoobjects can be formed either by the sputtering effect of the ion beam, which we call the nanomachining, or by locally inducing the decomposition of a properly chosen gas adsorbed on the sample surface, which is used for the growth of nanoobjects.
The goal of the thesis is a controlled creation of two- and three-dimensional nanostructures for photonic and sensor applications.
The available facility is a new multifunctional instrument based on a scanning electron microscope, FIB-type ion gun producing Ga+ ions, and a computer controlled gas injection system.
Qualifications: students of physics, chemistry, materials science and related disciplines.

Low dimensional semiconductor structures have been intensively studied for prospective electronic and photonic applications. Diploma or Ph.D. thesis will focus on the preparation of one-dimensional ZnO structures, investigation of their structural, electrical, and optical properties and description of the phenomena occurring when these nanostructures interact with gas molecules and electromagnetic radiation.
Infrastructure:
(I-V and C-V measurements in a wide range of temperatures, DLTS, conductive AFM, STM, Raman and optical spectroscopy, Low temperature photoluminescence, cathodoluminescence).
Qualifications: students of physics, chemistry, materials science and related disciplines.
Supervisors: Roman Yatskiv, Ph.D.; Jan Grym, Ph.D.; Jan Vaniš, Ph.D.
