Prof Zheng Vitto Han (Institute of Opto-Electronics of Shanxi University; visiting scholar at CNRS, Grenoble)
This course provides an overview of recent research activities related to 2D van der Waals (vdW) materials and heterostructures based on them, encompassing the fabrication of films/flakes, stacking (with potential for ordering and twisting angle) of vertical heterostructures, exploration of their electrical, optical, and magnetic properties, and demonstrations of prospective quantum devices. A brief introduction to future applications of vdW materials will be delivered in the concluding segment of the course.
Course will be presented in frames of Summer School 2024.
