Head Vlokh Rostyslav Orestovych, Registration Date 24-01-2005 Organization Institute of Physical Optics named after O.G. Vlokh of Ministry of Education and Science of Ukraine popup.description2 Band structure of space modulated ferroelectrics was theoretically described and its sensitivity to parameters of incommensurate modulation wave was established. On the base of Schredinger and Mattier equations solutions in the case of crystalline field disturbed by one-dimensional sinusoidal potential of modulated phase of single-axis ferroelectrics it was shown that electronic levels is sensitive to the attitude of periods of the crystalline field and potential of perturbation.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
