Superconducting-molecular interfaces


Contact Dr Oscar Cespedes to discuss this project further informally

Project description

This in an experimental project to investigate the origin and potential for the trapping of superconducting vortices, paramagnetic Meissner effect and the emergence and long diffusion of Cooper pairs and spin triplets at molecular/superconductor (SC) and molecular/metal/SC structures. By measuring molecular layers with and without metal interfaces, we will first determine the role of molecular distortion and the propagation of Cooper pairs in these structures. We will also confirm the presence of a spin ordering in proximity to superconductors and will determine the characteristic length of this effect.

Our previous results show evidence for the formation of vortex pinning via C60, a paramagnetic Meissner effect, and local magnetic fields in C60/Cu that could coexist with an induced superconductivity when deposited on top of a superconducting layer. The use of superconducting and/or magnetic electrodes to support long-range correlations that could extend throughout the system has the potential for impact on applications such as such eco-friendly transistors and magnetic memories. Superconducting proximity effects may lift the resistive limitation of normal-state contacts and pave the way to single spin and spin triplet transport in molecules.

Preserving the spin ordering without destroying superconductivity could open new paths to quantum computing and other carbon-based devices.

Entry requirements

Applications are invited from candidates with, or expecting, a minimum of a UK upper second class honours degree (2:1) in a relevant discipline, a Master's degree in a relevant discipline, or both.

How to apply

Formal applications for research degree study should be made online through the university's website. Please state clearly in the research information section that the PhD you wish to be considered for is 'Superconducting-molecular interfaces' as well as Dr Oscar Cespedes as your proposed supervisor.

If you require any further information please contact the Graduate School Office

If English is not your first language, you must provide evidence that you meet the University’s minimum English Language requirements.

We welcome scholarship applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates.  All scholarships will be awarded on the basis of merit.
