2D Materials

Presently, in our day-to-day life we interact with many interactive devices via different communications protocols: WiFi, Bluetooth, touch-screens, different sensing devices, etc., which in many cases take care of our security as well as of our health. All these devices require, in most cases, small size of elements, fast communication, and wide broadband for the data transfer. Such requirements from technology lead to the search of new materials or systems having new properties and which are the topic of the material science research or even fundamental condensed matter physics. As can be expected from the requirements of the planar technologies, such systems must have a reduced dimensionality and in this case the new phenomena start to define the transport properties of materials and systems.

Our aim is to use a novel combined approach of the fundamental and applied condensed matter physics studies of the graphene- and TMDs-based hybrid structures in order to fabricate the novel prototyping optospintronics devices. The first part is covered by the studies of the electronic structure and carriers dynamics in the graphene/TMDs structures via application of the complex 4D-ARPES spectroscopy (energy-, wave-vector-, spin, and time-resolved ARPES) accompanied by the state-of-the-art theoretical treatment. The input from these studies will be used in the fabrication process of the prototyping devices. We are going to use the feedbacks between two parts in order to understand the operation principles of the fabricated optoelectronics and spintronics devices on the basis of graphene and TMDs. Our approach will generate new knowledge which can be used in different fields of science and technology, like condensed matter physics, communications, sensing, biotechnology, etc.
