The observation of Shubnikov-de Haas and Hall oscillations in high-quality Bi2 − xCuxSe3 single crystals is reported. Measurements carried out upon rotating the samples with respect to the magnetic field demonstrate that the oscillations originate from two-dimensional surface states in three-dimensional single crystals and are determined only by the perpendicular component of the magnetic field.

Superconducting crystals of iron selenide FeSe are grown and their phase and elemental compositions are studied. The structural analysis of individual FeSe1 − x crystals showed the coexistence of two phases in this compound. The resistivities and magnetic susceptibilities of the crystals are investigated.

Single crystals of topological insulators—bismuth chalcogenides Bi2Te3, Bi2 − xSnxTe3, Bi2Se3, and Bi2 − xCuxSe3 with different charge-carrier densities—are grown by the modified Bridgman method. Their composition and structure are investigated and temperature dependences of the electric resistance and magnetic field dependences of the Hall voltage are obtained.

Layered oxycarbonate Bi2Sr4Cu2CO3O8 single crystals have been obtained for the first time by free growth in closed vapor-phase cavities. The morphology, structure, composition, and superconducting properties of these crystals have been investigated.

High-quality Bi2 + xSr2 − yCuO6 + δ (Bi-2201) single crystals with the ratio Bi/Sr = 1.4–2.0 were grown by the free growth method in gas-filled cavities in KCl solution-melt in a range of doping levels, which provides variation in superconducting properties from insulators to optimally doped crystals. The charge composition Bi : Sr : Cu = 1.7 : 2.3 : 2.5 with excess Sr and Cu and synthesis conditions provided growth cavity formation in the KCl solution at the crystal growth stage. Lamellar single crystals and whiskers were grown under quasi-equilibrium conditions of lowered growth temperatures and partial oxygen pressure, achieved in closed gas-filled cavities.

The Andreev reflection spectra of high-quality superconducting Sn1–xInxTe crystals with critical temperature Tc = 3.6–3.8 K were examined. The two-band nature of the superconducting state of this compound was established. The energy gaps have s-symmetry and were measured to be 2Δ1/kTc = 3.5 ± 0.9 and 2Δ2/kTc = 7 ± 1. Neither of the contacts with a resistance of 1.5–23 Ω revealed a peak at zero voltage typical of the topological superconducting state.

A comprehensive analysis of the evolution of the structural and superconducting properties of FeSe crystals stored in air for several years has been performed. It is established that the structure and phase composition of the samples remained invariable, while the superconducting parameters significantly degraded. These changes may be due to the stress relaxation or redistribution of defects in the samples.

Complex studies of the evolution of the structural and superconducting characteristics of Bi2212 and Bi2201 monocrystals depending on their storage in air for several years have been performed. It has been found that the sample structures remain perfect, whereas the superconducting parameters change due to oxygen mobility in the crystals. The character of the changes depends on the doping degree and the composition balance with respect to cations and oxygen in the grown monocrystals.
