2D semiconductors: applications and perspectives

The symposium will cover all relevant aspects of layered semiconductor materials: synthesis and chemical functionalization of these materials, their characterization with advanced techniques, and their applications in various fields. Special emphasis will be dedicated to a tuning of the electronic structure of these materials and to approaches for doping them.


Since the first reports on the exfoliation of an elemental layered semiconductor appeared in 2014, few-layer black phosphorus, as well as its monolayer, called phosphorene, has attracted great interest in the scientific community because of its direct band gap, which can be tuned with the number of layers, pressure, and electric field. Its high reactivity and puckered structure, which leads to anisotropic transport properties, have also drawn much research interest.

The field has seen rapid progress, and the family of layered semiconductors is continuously growing with new members, thereby bringing novel functionalities and increasing the variety of 2D-based semiconductor devices. These materials have been studied from a chemistry, material science, and physics point of view, with more to come.

The symposium includes sessions on various aspects of these 2D semiconductor materials: new developments in their synthesis, their characterization, their functionalization, and their theoretical modeling via DFT and other techniques. Applications of these materials in various fields (optoelectronics, catalysis, flexible electronics) will be given ample space, as well as for enabling technologies like functionalization, doping, and band gap tuning. Finally, the combination of these materials in van der Waals heterostructures will be included in the symposium.

The symposium has the dual aim of sharing recent results on novel layered semiconductor materials, as well as discussing the future road-map for the development of these materials. We strongly invite you to submit an abstract on your recent work on 2D materials. Abstracts will be selected with respect to the multidisciplinary intention of this symposium, which places itself at the focus of chemistry, physics, materials science, and device applications.

The symposium on ‘2D semiconductors: applications and perspectives’ at the 2019 E-MRS Spring Meeting will include a scientific workshop on black phosphorus and related materials, co-organized by the principle investigator of the EU Horizon 2020 ERC Project PhosFun (Dr. Maurizio Peruzzini).
