PhD in the Fabrication of Polariton Devices
Description: A polariton is part exciton, part photon and a goal of this and related research is to produce polariton lasers and light emitting diodes. Excitons are electron-hole pairs formed in semiconductors or in organic materials although these two materials acts as hosts to different types of exciton: Wannier excitons are formed in semiconductors and have small binding energies and large radii whereas Frenkel excitons are much more strongly bound, have small radii and are typically found in molecular materials. Thus polaritons formed from organic materials should operate at room temperature. The project will involve three partner groups at University of Sheffield, FORTH and the University of Southampton to design and produce an organic microcavity a structure that enhances the interaction between the Frenkel excitons and an optical field formed by two mirrors. One of these will be formed from alternate layers of inorganic semiconductors and the other from alternate quarter wave layers of dielectric materials. The organic material will be a thin self-assembled J-aggregate dye. Testing of these structures will require continuous wave and time resolved spectroscopy.
Due to the work to be carried out candidates should have a background in organic semiconductors
Required education level: Upper second class degree or better
Degree field: Physics, Physical Chemistry, Electrical Engineering
Contact: Prof. Raymond Murray
