Design and Simulation of Waveguide-Based Devices in 2D Dirac Materials

This workshop talk explores advanced quantum mechanical modeling techniques for the design and simulation of electrostatically induced waveguides in 2D Dirac materials. The focus will be on nanoelectronic devices such as dot resonators and 50/50 splitters in graphene, as well as valley filtering in 8-Pmmn borophene for emerging valleytronic applications. Highlighted is a novel conservative fourth-order real-space method, which ensures superior accuracy and efficiency in simulations. Participants will gain valuable insights into the theoretical foundations, practical challenges, and innovative applications of electrostatically induced waveguides in future nanoelectronic and valleytronic technologies.
