Dr. Oriol López Sánchez He is a Telecommunications Engineer from Polytechnic University of Catalonia (UPC) in Barcelona with a PhD in Microsystems and Microelectronics at École Polytechnique Fédérale de Lausanne in Switzerland (PhD Thesis: Optoelectronic devices based on Transition Metal Dichalcogenides). In the present he is working as a postdoctoral researcher at the Laboratory of Nanoscale Electronics and Structures in EPFL.
The discovery of graphene marked the start of research in 2D electronic materials which was expanded in new directions with MoS2 and other layered semiconducting materials. They have a wide range of promising potential applications, including those in digital electronics, optoelectronics and flexible devices. Combining 2D materials in heterostructures can increase their reach even further.
In this talk, I will review the status of our research in 2D transition metal dichalcogenides (TMDCs) and present our current level of understanding on the influence of contacts, material quality and the environmental effects on 2D materials, all critical for achieving high performance levels in devices based on 2D semiconductors. I will also update on our efforts to achieve high operation frequencies in scaled TMDC devices and our recent work on electromechanical response of MoS2.
