In many organic semiconductor and biological pigment-protein complexes, a single photon produces a pair of spin-entangled excitations. The nature and behavior of these entangled excitations is an active area of study as many fundamental questions remain unanswered, despite their potential applications in solar energy harvesting, sensing and even quantum communication. In this project you will use magnetic-field-dependent time-resolved spectroscopy to map spin decoherence in organic semiconductors and biological pigment-protein complexes and to determine the material parameters that control it.
I am seeking to hire PhD students to work on projects across the physics/chemistry/biology interface. My group’s expertise lies in tracking electronic excited states with time-resolved spectroscopy as they move through molecules, pigment-protein complexes, photonic structures and organic semiconductor devices. I offer a dynamic and international work environment with world-class facilities in a city famed for its beautiful countryside and city-wide cultural events.
In this project you will study the magnetic-field dependent spectroscopy of organic semiconductors using pulsed lasers (femtosecond-picosecond) to map the spin-decoherence timescales as well as mapping the electronic landscape of the processes.
You will be trained in ultrafast spectroscopy and optics in Sheffield’s Lord Porter Ultrafast Laser Facility. You will learn data analysis of big data sets and programming (mainly Python). You will work within a dynamic and international group of young scientists from across the departments of physics, chemistry and biology.
You will have a 2:1 or above (or equivalent degree) in physical chemistry, physics or material science. I am looking for hard-working and enthusiastic students.
