About Professor Mróz

Professor Stefan Mróz, the well-recognised physicist, is going to retire this year. In order to recognise his outstanding contributions to surface science, and acknowledge his work for the academic community, the Institute of Experimental Physics of the University of Wrocław is organizing a special symposium. Professor Stefan Mróz Symposium is meant as a two-day scientific meeting (16-17 May 2008), consisting of invited lectures of outstanding scientists, oral presentations and poster contributions of researchers.

Born: 1938 Rzeplin (administrative district Tomaszów Lubelski).

Activities: From the beginning of his career Professor Stefan Mróz has been dealing with surface science. During his Ph.D. work he constructed a glass reverse view LEED apparatus and with the use of this equipment he performed investigations of thermal vibrations of atoms on the Ni(001) surface. After completing his Ph.D., in collaboration with Dr. Stanisław Kaszczyszyn, Professor Mróz developed his experimental setup in order to make a chemical analysis of solid surfaces possible with the use of Auger electron spectroscopy, which extended its utility. Both methods were implemented by Professor Mróz for the first time in Poland. Professor Mróz continued investigations of thermal vibrations together with Dr. Alicja Mróz and Dr. Andrzej Grudniewski, and also performed experiments concerning the sulphur segregation on metal surfaces.
After habilitation (1976), structural investigations of ultrathin epitaxial metal layers on substrates attracted attention of Professor Mróz. Together with his co-workers he developed novel applications of Auger electron spectroscopy and elastic peak electron spectroscopy in order to determine parameters crucial for a quantitative Auger analysis, such as the inelastic mean free path of electrons in solids and the backscattering factor in Auger electron emission. Based on the results obtained together with Dr. Alicja Mróz he indicated the possibility of using the crystalline effects in Auger electron spectroscopy to determine the structure of ultrathin layers. As a consequence, he developed together with Dr. Marek Nowicki the directional Auger (DAES) and directional elastic peak electron spectroscopies (DEPES). With the help of these new experimental methods, it became possible to find the crystalline structure of epitaxial layers using a very simple and inexpensive apparatus. Recently, together with his co-workers and Ph.D. students in the Electron Spectroscopy Department, Professor Mróż works on new applications of DAES and DEPES for determination of the composition, crystalline structure, and structural changes in surface layers of metal alloy crystals.

The most important scientific achievements of Professor Stefan Mróz:

  1. Experimental determination of the thermal vibration amplitude of surface atoms on different nickel crystal surfaces and determination of the vibration anisotropy [3,13,22].
  2. Determination of inelastic mean free path values and backscattering factors for Au, Ag, and Cu [38,46,47,56,60,61].
  3. Elaboration of the physical principles of DAES and DEPES [66,75,79,85].
  4. Investigation of the growth mechanism and the crystalline structure of metal layers on metal substrates at different temperatures [63,68,84,90,91].

The most important achievements of Professor Stefan Mróz concerning the development of electron spectroscopy methods:

  1. Construction of the glass reverse view LEED apparatus [5,25].
  2. Development and application of an alternating current method of measuring the diffracted beam intensity in LEED [13].
  3. Elaboration of a simplified quantitative Auger analysis method [36,72].
  4. Application of a simplified version of the DEPES method to determine the composition of the first few atomic layers of Cu3Au(001) [99].

The results of investigations of Professor Mróz, obtained mainly in collaboration, were presented in 103 publications. 74 works were published in international scientific journals. Moreover, Professor Stefan Mróz published three books and five popularization works. He is also a co-author of three patents. Professor Mróz achieved two individual and one joint Award of the Polish Minister of Science and Higher Education and a number of awards of the Rector of the University of Wrocław. He supervised about 60 M.Sc. and 9 Ph.D. theses. Two of his Ph.D. students made habilitation and one of them became a professor.
