Synthesis and Printing of 2D Materials

2D materials are nanomaterials that consist of a single layer of atoms. Due to their unique structure, these materials have extraordinary properties: 2D materials have an increased surface area - to –volume ratio, which makes 2D materials chemically more reactive than their bulk counter parts. Confinement of the electrons in one plane alters the band structure giving 2D materials new electronic and optical properties (ranging from extremely high conductivity of graphene to semiconducting properties). Last not least, the atoms in the monolayers are held together by covalent forces, 2D materials can be very strong. 2D materials have found use in many applications as additives or in electronic devices.

Our group focuses on the synthesis of 2D materials by liquid phase exfoliation, formulation of inks for printing, as well as the integration in devices by printing. The following types of 2D materials are synthesized and used in our lab:

  • MXenes (2D transition metal carbides and nitrides)
  • Graphene
  • Transition metal dichalcogenides (MoS2, WS2, MoSe2, WSe2, MoTe2)

We apply 2D materials in printed transistors, sensors and supercapacitors.
