摘要： The object of the invention is a method of producing a three-dimensional TI micro- or nano-heterostructure characterized by the fact that, directional crystallization of a single-phase liquid of eutectic, peri-eutectic i.e. supereutectic or subeutectic into at least two-phase composite heterostructures, the resulting composite heterostructures containing a topological insulator TI and another material, which other material is selected from a group including one or more insulator, semiconductor, metal, other Tl, ferroelectric material, ferromagnetic material, superconductor, optically active material. Another object of the invention is a three-dimensional micro- or nano-heterostructure of TI produced by the method according to the invention, characterized in that it is multilayered and is a eutectic, peri-eutectic, super-eutectic or sub-eutectic composite consisting of at least two crystalline phases comprising a phase of TI and a phase of another material, which other material is selected from a group including one or more of an insulator, semiconductor, metal, other Tl, ferroelectric material, ferromagnetic material, semiconductor, optically active material.
