Project content

Task of project:

Experimental studies of proper and induced optical effects in low-symmetric solid and liquid crystal materials and filled nanoporous structures are aimed to solve an important scientific and technical problem of materials science and nanophysics, namely: increasing the efficiency of the structures as promising working elements of electro-, piezo or acousto-optical devices for infocommunication, including defense systems, as well as optoelectronic sensor elements of micro- and nanoelectronics.

Object and subject of research:

The object of research of this work is innovative low-symmetric solid and liquid crystal materials and filled nanoporous structures. The subject of this work is the proper and induced (electro-, piezo- or acousto-) optical effects in the corresponding materials and fabricated nanocrystal structures with a preset anisotropy.

The purpose and main objectives of the study:

The main goal of the project is to develop scientific and technological principles for simulation, creation and research of innovative low-symmetric and nanostructured crystal materials with a defined crystallization geometry (i.e. with a preset anisotropy) of the given material and to evaluate the prospects of their applications in various optoelectronic devices. This involves the use of a large undiscovered resource of spatial anisotropy of induced optical properties of the material. The main objectives of the project were: 1) conducting of the necessary experimental studies of induced (electro-, piezo- or acousto-) optical parameters for the selected promising crystal material; 2) application of the developed technology for the most efficient use of anisotropic material to find the appropriate extreme geometry of the studied effect in the material; 3) on this basis developing of the technology of creating nanostructures with a preset anisotropy, using nanoporous matrices from alumina and 4) conducting of proper and induced optical studies of created nanostructures filled with solid material in the extreme geometry of the induced optical effect and analyzing of a practical use of the creative nanostructures.

The main results

  1. The information technology of the most efficient and stable use of anisotropic materials created by the authors was improved and its approbation was carried out on the example of crystals of group Ba(NO3)2, KDP and other low-symmetric crystalline materials.
  2. The software for 3D analysis of spatial anisotropy and search of extreme value of induced optical effects were improved and its approbation was carried out on the examples of investigated crystals.
  3. The methods previously developed by the authors were used to determine the non-zero components of tensors of electro- and piezo-optical effects and the parameter of acousto-optical quality in crystals of different classes of symmetry; For the first time, methodological support was created for experimental measurements of nanostructures with a preset anisotropy.
  4. Nanocrystal structures were created by filling the pores of nanoporous matrices with water-soluble crystal materials.
