We seek a PhD student who will be an integral part of a joint research team between the University of Hull and the University of the Sheffield working on the development of efficient organic light emitting field effect transistors (OLEFET) for the realisation of net gain in organic laser devices. To achieve a net gain it is necessary to strongly confine the electromagnetic field surrounding the emitting material and generate effective optical feedback. Our research vision is to develop organic based light emitting field effect transistors coupled to a high quality photonic or hybrid/plasmonic cavities. The planar geometry of OLEFET will allow us to integrate either vertical or lateral optical cavities within the device channel with no overlap between the recombination zone and the metallic electrodes leading to almost a lossless electrically-driven light emitting optical resonator, a device that is key ingredient to achieve net gain in organic laser devices.

The student will be in charge of the development of techniques that will allow the integration of light emitting field effect transistors into photonic or hybrid photonic/plasmonic cavities. This will require the use of wide range of fabrication techniques such as spin-coating, high vacuum deposition techniques for wide range of materials (organic, dielectric and metal), optical and electron beam lithography techniques. The fabricated samples and devices will be tested and characterised using wide range of electrical testing and optical spectroscopy facilities. You will be part of Nano3 research group in Hull and the Electronic and Photonic Molecular Materials Group in Sheffield.

Applicants should have a 1st/2:1 class undergraduate degree qualification in physics, material science or electrical engineering, together with good experimental skills.

As a PhD student, you will take the Postgraduate Training Scheme at the University of Hull and may study any part of the Doctoral Development Programme at the University of Sheffield. Upon the completion of the joint doctoral degree programme, you will be awarded a Doctor of Philosophy Joint from Hull and Sheffield (subject to ongoing discussions).
