PhD project: Terahertz spintronics: Enabling the exploitation of electron spin
Supervisor: Dr Darren Graham


Recently, the emission of extremely broadband electromagnetic radiation, spanning from the mid- to far-infrared spectral regime and covering the so-called ‘terahertz gap’ in the spectrum, from ferromagnetic structures has led to an exciting new route for the generation of terahertz radiation. The ability to control the properties of the emitted THz radiation also has the potential to facilitate a wide range of diverse, technologically demanding scientific applications, from improved medical diagnosis to non-destructive testing and advanced airport security scanners. Furthermore, by understanding the fundamental emission process we will be able to establish new characterisation tools for use in developing the next generation of spintronic devices, where ultrafast spin processes are being investigated for data storage and manipulation.


In this project the student will use the state-of-the-art laser facilities within the Photon Science Institute to reveal the physics that governs the properties of this remarkable materials system and optimise spin-based structures for the emission of THz radiation. This work will involve using a range of laser spectroscopic techniques including using femtosecond laser systems to perform ultrafast terahertz spectroscopy.


This work will be carried out in close collaboration with several industrial companies. The opportunity to work in collaboration with both international renowned academics and world-leading industrialists will provide training in cutting-edge experimental physics techniques and business awareness. The skills gained will provide a solid foundation for a future career in industry or academia.
