Doctoral Studies

Plasma physics - Field

Brief description of field

The field of study is oriented on experimental and theoretical research in the field of non-isothermic plasma excited at both reduced and atmospheric pressure. In most cases it concerns high frequency and microwave plasmas. One part of this research focuses on the development of diagnostic methods of the plasma of electric discharges by the spectral, microwave, corpuscular or probe methods. The studies of elementary processes taking place in plasma are, as well as the above methods, conducted using radio spectroscopic (EPR) methods in the gas phase. A substantial part of this experimental research is aimed at plasma chemical reactions, which can, at present, be applied in a number of industrial technologies. They are above all the plasma chemical preparation of thin layers of plasma polymers, hard and super-hard layers of the diamond type with nano-composite layers. Another object of plasma chemical research and development is the surface treatment of solid substrates (most frequently polymer materials) in low temperature non-isothermic plasma for the purpose of achieving the required change in their properties (adhesivity, hydrophility, hydrophobity, semipermeability with respect to different gases and liquids). There are also developed new plasma chemical methods of restoration and preservation of archaeological finds and museum objects. A part of this experimental work is also aimed at new plasma chemical methods of disintegration and liquidation of ecologically noxious substances and in search of new economically advantageous ways of ozone generation.

Profile of a typical graduate

The graduate has a relatively universal education in the field of the diagnostic methods of plasma and the surfaces of solid substances. He/she can relatively easily become adapted to other spheres of science, such as electronics, electro-technology, microwave technology, physics of the ionosphere, microelectronics and special chemical technologies. Due to the character of the study he/she is capable of understanding the hardware aspect of computer technique, controlling technological processes with the computer, etc.. The graduate is able to employ the fundamental computer modelling of the elementary and chemical processes in plasma. Graduates can make themselves useful as pedagogical and scientific workers at faculties of universities with science and technical orientation. They are now well accepted as research workers in the research institutes of the Academy of Sciences of the CR and research institutes of the ministry. They assert themselves as development workers in microelectronics (plasma chemical etching and layer deposition, monitoring processes), powder metallurgy, quantum electronics (gas lasers and laser interferometers) and in the material engineering and chemical industries. Part of the graduates assert themselves in leading functions at central offices, ministries and the managements of important enterprises and institutions.

Requirements for applicants

Graduates of the master or engineering studies of the respective orientation. Fundamental knowledge of the phenomena in ionised gases and plasma kinetics. A good orientation in fundamentals of atomic physics, quantum mechanics, quantum electronics and microwave electronics. In some experimental plasma chemical topics, allergy to the stated substances must be excluded, to which he/she will come in contact in generally harmless concentrations. Ability of active communication in English and/or another world language are an pre-requisite.

  • Active participation in seminars of DPE. Every year a lecture publishing the results achieved (O/1).
  • Fulfilling teaching duties – to be in charge of experimental and theoretical exercises to the extent of 0/4 in either term.
  • Elaboration of the dissertation thesis.
  • Presentation of the dissertation thesis.
  • Publication of an article in a journal.

Content and extent of the state doctor examination, required knowledge

Collision processes in plasma, Kinetics of the individual components in plasma. Types of dividing functions and their measurement. Transport process in plasma. Dielectric properties of plasma. thermodynamics and magnetohydrodynamics of plasma. Strongly ionised plasma. Spectral, probe, microwave and corpuscular diagnostic methods. Fundamental technologies utilising plasma excited at low and high pressures. Plasma chemical processes. Spreading of electromagnetic waves in plasma. List of vacuum techniques.

Requirements of the doctorate dissertation thesis

The dissertation thesis must, besides the background research element, contain the candidate’s own, absolutely original results. A condition of admittance to the presentation and discussion is the publication of his/her own results in renowned technical literature, and/or confirmation of the acceptance of the contribution to the press. If it concerns a team of authors, the dissertant must be the chief author. The paper may be presented in either the Czech or English language. In the case of a binational study (this possibility exists at present in France and Germany), it is necessary to present the paper in the language approved by the purtenant multinational committee.
 
List of modern topics of dissertation theses for the given academic year is given below at the page.
