Numerical Study of Interference and Dephasing in 2d Materials for Sensing Applications
Abstract
In recent years, graphene and other 2D materials have become highly promising for a wide range of next-generation technologies. In these materials, quantum effects can play an important role, and there is significant interest in exploiting these effects for useful applications. In this project, we will develop and use numerical simulations to explore how quantum effects in graphene can be exploited for various sensing technologies. First, we will study the efficiency of rotation sensors based on electron interference in graphene. Such sensors may be employed as gyroscopes in personal navigation systems that do not rely on GPS, and would be smaller, lighter, and cheaper than the current technology. This work will be carried out in collaboration with experimental efforts at the Stevens Institute of Technology. In parallel, we will study the role of dephasing in graphene and other 2D materials. Dephasing, which involves the transfer of energy between electrons and other particles, destroys quantum interference but may itself be exploited for sensing applications. We will develop a simulation tool to study the transfer of energy between charge, heat, and spin in realistic models of graphene and other 2D materials. We will explore the fundamental nature of these energy transfer processes and how they may be used in novel sensing technologies.
