Workshop 1: Twistronics and Topological Phenomena

The workshop will address emerging quantum transport properties in multilayer 2D materials based on interface engineering and twistronics applications.  A particular focus on the impact of magic angles on electronic, vibrational or magnetic properties as well as topological phases occurring in such systems. Impact on spin transport properties and other topological phenomena will be also considered.

This workshop will focus on the progress of the chemical approaches towards graphene and related 2D materials. Top-down chemical exfoliation and bottom-up growth and synthesis of GRMs, as well as the chemical functionalization of GRMs with covalent and non-covalent approaches leading to tunable properties will be presented. Other topics including hierarchical hybrid structures, polymer composites, solution processing, electrocatalysis & photocatalysis, functional foams, membranes and coatings of GRMs will be also presented.

This workshop aims at presenting recent theoretical advances and simulation studies of optical, magnetic and spin transport phenomena in graphene, two-dimensional materials (2DM), as well as more complex vdW heterostructures. Emphasis will be given to concepts such as valleytronics, dynamics of excitons, as well as the emerging field of twistronics. A particular focus will be also given to the physics emerging from 2D magnetic materials and their interfacing with other 2DM such as TMD and others to trigger spintronic applications.

The workshop focuses on recent advances and challenges in the characterization of 2D materials, van der Waals architectures and 2D material-based devices. Properties and phenomena investigated at the mesoscopic, nano and atomic scales using diverse advanced techniques will be covered, e.g. growth, defects, chemical functionalization, heterojunctions, charge transfer and dynamics, light emission, device operation. The scope will include a wide range of characterization methods that are critical for the study of 2D materials, such as microscopy, spectroscopy and transport / photo-transport measurements. The workshop will also address multimodal/multidimensional approaches that allow a simultaneous acquisition of several information channels (e.g. structural/chemical, structural/opto-electronic…), in-situ manipulations, time-resolved measurements and operando characterization.

A series of targeted talks given by Invited speakers will be followed by oral contributions selected from the Graphene 2021 submissions on all workshops mentioned above.
