The main project objective is to understand the effect of interaction of selected transition metal dichalcogenides (TMDC) on the properties of graphene in hybrid systems at the nanoscale. In particular an effort will be directed to the system where graphene is combined with 1T-TaS2 and 1T-TaSe2. The mentioned TMDC are characterized by successive first order phase transitions related to charge density waves (CDW), distinct insulator to metal transition and high value of spin-orbit coupling (SOC). Graphene combined with TMDC gives the unique possibility of synthesizing a material which allows to generate spin polarized charge carriers, to control their motion and to detect them. This gives a chance for application of graphene, with its unique transport properties, in the system produced for spintronic. The TMDC and graphene itself are not able to provide the desired physical parameters, but combined become a real candidate for building the new hybrid materials for novel computer systems. However, the first step is to comprehensively describe the basic mechanisms and phenomena, which occur on the interface of graphene and TDMC in the hybrid system. The project contributes to the understanding of a new physical and chemical processes and in consequence it allows to supplement the currently developed model of interactions. This will be possible inter alia basing on the materials, which allow for modification of their electrical structure by transition from three- to two- dimensional form. In particular the project will answer the following questions:

• is it possible to achieve the two-dimensional limit in hybrid preparation,
• is it possible to observe charge density waves phases by STM technique in hybrid systems, even though tunneling process takes place over graphene,
• whether spin-orbit coupling survive in graphene/(ML)1T-TaS2 , graphene/(ML)1T-TaSe 2 hybrids,
• is it possible to observe enhancement of the spin-orbit coupling in the graphene/(2D)1T-TaS2 , graphene/(2D)1T-TaSe2 hybrid system,
• to what extent in hybrid systems the MIT phase transitions in TMDCs changes the electronic structure of graphene,
• how TMDCs in graphene/TMDC hybrids modify graphene electronic structure in the vicinity of zig- zag and armchair edges in nanoscale

The planned investigations allow to gather the knowledge related to physical phenomena responsible for graphene properties in the hybrid systems based on two-dimensional transition metal dichalcogenides. Such knowledge will significantly affect the development of science and allow in the future for conscious approach to designing the materials for spintronic. In the wider perspective the proposed research becomes the base for development of materials which will be the building block of new generation of computer systems. This enables changes in the future information technology.
