Faraday Rotation in Organic Semiconductors


Society's over-reliance on information exchange around the world hinges critically on ultrafast data communication using light signals.  Modern optical data communication works at high bit rates and therefore polarisation switches have to be very fast (<1ns).  Understanding dynamics of polarisation decay and dispersive transport of excitons as a function of device morphology is critical in underpinning material parameters required developing ultrafast polarisation switches.  This project will use a range of complementary experimental approaches to study polarisation switching and Faraday rotation in an emerging class of organic semiconductors.

Program type



This research project intersects physical chemistry, material science and chemical physics.  Students will investigate optical properties of π‐conjugated materials using polarised light spectroscopy such as Circular Dichroism, Optical Polarimetry, and Cicularly Polarised Luminescence.  A more challenging part of the project will be to develop cutting-edge methodologies to allow for investigation of time-resolved excited state properties sensitive to polarised light.

Additional information

The project is particularly of interest to students who are inclined towards physical chemistry or chemical physics with focus on optical spectroscopy leading into the field of laser spectroscopy.  Prospective students should have a strong command in physical chemistry with an equivalent minimum cumulative GPA of 3 (out of 4) or CPI of 9 (out of 10) or a First Class Honours degree in their undergraduate programmes.
