Organic Spintronics: investigating planar polymeric spin-valves, to determine the variables which influence the spin transport in the devices and aiming to achieve the largest spin current possible
Organic spintronics is the study of the transportation of spin carriers through organic semiconductors. Recent research has found that the interface plays an important role in the spin transportation, and that planar spin-valves are likely to have more benefits than vertical spin-valves. This project investigates planar polymeric spin-valves, to determine the variables which influence the spin transport in the devices, along with aiming to achieve the largest spin current possible. The devices will be patterned using e-beam lithography, with the magnetic electrodes then evaporated on top. The polymer will then be spin-coated on top. Different magnetic electrodes (NiFe and FeCo) and different polymers (P3HT and PBTTT) will be investigated to determine how they influence the spin transport. The devices will be characterised using 4-probe resistance measurements, along with magnetic characterisation and surface analysis (AFM, XPS).
