Laboratory of electronic and spin structure of nanosystems under the leadership of Prof. E.V. Chulkov (University of the Basque Country, Spain) was found in 2015 year and funded by St. Petersburg State University.

 

Laboratory efficiently combine work on the most promising materials for use in the rapidly developing high technology areas of modern industry spintronics and nanoelectronics simultaneously in three essential areas: (a) study the features of the electronic and spin structure of highly prospective complex quantum nanosystems with enhanced spin-orbit and exchange interaction, both by experimental and theoretical methods, (b) the development and use of direct methods for the extra high vacuum synthesis of studying nanosystems during the experiment and controlled changes of parameters of synthesis in dependence on the desired features of the electronic and spin structure (c) analysis of the possibilities of using the studied systems and their combinations in spintronics with possibility of direct synthesis and study of functional models of the active elements for new generation of spintronic and nanoelectronics devices. Directly in the framework of the project the investigations will be carried out in the following areas:

1. Spin-dependent photoemission and transport in topological insulators.

2. Spin-dependent phenomena in graphene-like systems.

3. Spin-dependent phenomena and transport in the Rashba systems with enhanced spin-orbit interaction.

4. Study of heterostructures based on combinations of graphene/topological insulators, graphene/ systems with giant Rashba splitting.

 

The high level and quality of the proposed studies is additionally supported by the use of the modern equipment available at the resource center of Researcher Park SPbSU "Physical Methods of Surface Investigation", Russian-German laboratory at BESSY II (Helmholtz-Zentrum Berlin) and other resources of European light sources.

 

Experimental investigations (ARPES, XPS, Spin-resolved PES, Kerr effect, AFM, STM, LEED).

Theoretical investigations (Ab initio methods of quantum band theory of solids within the DFT, the pseudopotential method and the method of linearized augmented plane wave)

Synthesis and electro-physical investigations (Bridgman method, CVD, MBE)
