Nanoscale Transport and Optoelectronics

We are a research group specializing in nanoscale electronics and optoelectronics. Our main focus is two-dimensional atomic crystals – a recently discovered class of materials that are only atoms thick. These include:graphene, atomically thick form of carbon with record electrical conductivity, thermal conductivity, and strength; monolayer transition metal dichalcogenides (MoS2, WSe2,MoSe2), semiconductors strongly interacting with light, and monolayer boron nitride (BN), an atomically-smooth insulator material. Our overarching goal is to answer the following questions:

  • How does one controllably create, pattern, and manipulate two-dimensional atomic crystals? Is it possible to manipulate properties of these materials by cutting them or by stacking them into heterostructures?
  • What happens to interacting electrons that are confined in two dimensions and are governed by the laws of quantum mechanics? How do they interact with light? Is it possible to create electronic circuitry and optoelectronic devices that are based on graphene and other two-dimensional atomic crystals?
  • What are the mechanical properties of atomically-thick materials? Can we use nanoelectromechanical devices based on graphene to sense ultrasmall forces and weigh ultralight objects?

We are equally interested in potential applications of our research. We would like to explore the potential of graphene and other two-dimensional materials towards applications in electronics; design nanoelectromechanical mass and force sensors capable of weighing individual atoms; create graphene biosensors for biomedical applications. 

Note: The group is currently moving from Vanderbilt University in the US (where we were based previously for five years) to Freie Universität. Please see the webpage of the group at Vanderbilt for more details.
