Name of the project:

Creation of the Laboratory of Crystallography

Research directions: Physics and astronomy

Goals of project:

Searching for methods of the creation of new photonic and optoelectronic devices with specified optical properties determined by the modifications of their crystalline structure

Project objective:

Creating new materials based on halide perovskites using heteroepitaxy, modification of the inorganic framework, functionalization of organic cations and controlled introduction of defects to augment them with new functional properties.
Researching the possibility of using created novel materials and structures in various domains of photonics, including information photonics, white luminophores and polaritonic devices functioning at room temperature.

Scientific results:

A method for synthesizing heteroepitaxial structures based on halide perovskites has been developed.
New perovskite-like crystal structures of lead halides have been discovered, for example, with a topological hyper-star lattice.
The phenomenon of spin noise has been discovered in halide perovskites for the first time.
Resonant diffraction gratings based on halide perovskites have been created using focused ion beam irradiation.
Photon echo in single crystals and thin films of halide perovskites has been studied.
A bound state of two excitons, a biexciton, has been discovered in chloride perovskites.

Education and personnel occupational retraining:

1 PhD thesis was defended.

Cooperation:

Prof. Pavlos Savvidis (Quantum Optoelectronics Lab, Westlake university, Hangzhou, China)
Prof. Zhijun Ning (Shanghai Tech University, China)
