Method of creation of low-defects A3B5 semiconductor heterostructures by layer-by-layer monocrystal assembly. Raw materials (Ga, As, Al, In or dopants) are evaporated in ultrahigh vacuum conditions from effusion cells. We are experienced in growth of InGaAs/GaAs and GaAs/AlGaAs quantum wells with inhomogeneous broadening lower that radiative linewidth of excitonic resonance. Other possible structures: Bragg mirrors and microcavities, planar waveguides, thick quantum wells, special profile quantum wells (triangular, parabolic etc.)

In reflection spectroscopy laser light reflected from the sample is studied. We could carry out experiments at temperatures from 1.5 to 300 K and magnetic fields up to 7 T. Laser light sources: broadband femtosecond Ti:Sapphire lasers. Brewster geometry allows to simplify spectra identification and separate determination of radiative width and nonradiative broadening of excitonic resonances in A3B5 quantum wells samples.

In PL spectroscopy a luminescent response from the sample is detected at laser light pumping either above quantum well barrier, or in resonantly. Available pump lasers are: semiconductor non-tunable (532, 650, 1064 nm) or tunable lasers, or tunable Ti:Sapphire laser. We could carry out experiments at temperatures from 1.5 to 300 K and magnetic fields up to 7 T. Time-resolved PL could be detected by the streak-camera with femtosecond laser pump.

In our RC we have a setup with femtosecond Ti:Sapphire lasers, delay lines, photoelectron multipliers, streak-camera. This setup allows one to study free induction decay, resonant Rayleigh scattering, four-wave mixing and photon echo etc.

Atomic force microscopy relates on van der Waals' interaction of cantilever's tip with a sample surface. It provides opportunities of subnanometer accuracy microrelief analysis and magnetic and electrophysical properties study with several ten nanometers spatial resolution.

Microwave radiation in chemical synthesis provides quick and uniform heating of the reaction mixture without contact with the heating element which grants high reproducibility and selectivity, so the method is indispensable for long and precision syntheses. Furthermore, microwave reactor allows to carefully monitor and control the reaction parameters (temperature, pressure, and radiation power t. D.).

Ultrasonic chemical synthesis is widely used in materials science to produce materials of different geometry and composition. Ultrasound effect on the medium leads to various processes, such as dispersion, sonolysis, ostwald ripening, cavitation, etc. Varying the parameters of the reaction conditions provides a wide range of functional materials.

Hydrothermal chemical synthesis in an autoclave at high temperatures and elevated pressures provides unique conditions which are used to obtain monocrystals and particles of substances which are unstable near the melting temperature or insoluble in water and other solvents under normal conditions.

Dip-coating is a method of thin films or particles deposition on a substrates or fibers or complex shape objects, which is in fact immersing and lifting of the sample from precursor solution. High uniformity of movement of the substrate provides high quality films with good reproducibility.

Spin-coating is a method of thin films or particles deposition on planar substrates by centrifugation and spreading the precursor solution on the sample surface. Spinner allows varying conditions (rotation speed, acceleration, and so on) with great accuracy, which grants producing thin films of a given thickness and composition.
