Research Group Summary.

Professor Jamie Warner's group is based in the Department of Materials and study nanostructured materials ranging from 2D Crystals (graphene, BN, MoS2, WS2 etc), 1D wires and nanotubes, to 0D quantum dots. Interests are in developing nanostructures with unique properties that have potential in electronic, photonic, and energy applications. We are a multi-disciplinary group that collaborates extensively with a wide range of scientists within Oxford, UK and internationally.



We conduct fundamental and applied research in the following areas of Nanostructured Materials:

-Synthesis.

-Chemical functionalization, processing and purification.

-Bottom-up self assembly and top-down lithography

-Atomic resolution imaging using aberration-corrected transmission electron microscopy.

-Optical spectroscopy (Photoluminescence, Absorption and Raman).

-Electronic and opto-electronic device fabrication and characterization.
