Studies in the field of dielectric physics relates to fundamental research that has made a significant contribution to the development of this field of science. The results of our research have received worldwide recognition and are published in such prestigious international physical journals as the Journal of Applied Physics, Applied Physics Letters, Ferroelectrics, Transactions of IEEE and others. The new concept of interrelation of polarization and volume charge in polymer ferroelectrics and electrets put forward by ONAFT scientists was further developed in the joint work of the department teachers with leading foreign scientists, such as Prof. H. von Seggern (Darmstadt Technical University, Germany), Prof. J. Marat–Mendes (Lisbon New University, Portugal), Prof. J. A. Giacometti (University of São Paulo, Brazil). The staff of the department takes an active part in international scientific forums, conferences and symposia. The results of the researches are introduced into the educational process in teaching of general physics courses, section “Electrostatics: properties of dielectrics”, as well as special courses in physics of dielectrics.

  1. Scientific field: “Physics of phase transitions and critical phenomena in inhomogeneous systems” under the direction of Professor V. B. Rogankov. The main goal of many years of scientific research is the development of new materials of electronic equipment with ionic conductivity and technologies for their production, the study of the physical and chemical properties of thin films of superionic conductors and the development of sensors of oxygen, halogens, ammonia and freons based on them.

The study of phase transitions and transformations in solutions whose basic component is one or more molten organic salts, called ionic liquids, is a relatively new, but very promising area of ​​research, including the development of modern high technology. In particular, such important applied problems as the transformation of solar energy into thermal and electrical, with the accompanying search for new methods of efficient heat transfer and the accumulation of solar energy, can be solved with solutions of ionic liquids, as it is planned to substantiate as a result of the conducted research. The use of new nanomaterials will significantly increase the efficiency of energy conversion in solar installations.

Evidence of recognition of the scientific achievements of Professor V. B. Rogankov and his followers is the active cooperation with such well–known scientists as Prof. M. Fisher and Prof. M. A. Anisimov (University of Maryland, USA), Prof. G. Smith (Salt Lake City University, USA), Prof. J. Schmelzer (Bochum University, Germany), cooperation with other universities, in particular in Hungary.

21 articles of Prof. V. B. Rogankov are registered in the scientific base of Scopus and 67 foreign scientists refer to his work. The citation index of his articles (H = 6) is one of the highest among ONAFT teachers.

The basic model of fluctuation thermodynamics is described and illustrated by the relevant data for pure IP. The research results are outlined in a monograph published by Prof. V. B. Rogankov in English in 2016. In the following stages, a new validated methodology for predicting the properties of pure IPs and their solutions in the field of phase transitions and critical solution lines is envisaged.
