Imperial College London Job Description Job Title Research Assistant in the Development of Novel Printable Organic Field-Effect Transistors Department / Section Department of Physics, Experimental Solid State Physics group and the Centre for Plastic Electronics Location South Kensington Campus Reporting To Dr. Alasdair J. Campbell Working Closely With Other Research Assistants and students in the group and in the Department of Chemistry. Grade Academic & Research, Level A Working Hours Not normally less than 35 hours per week Fixed-Term Until 31 December 2013 Summary of Post This is to carry out research on fully-printable organic field-effect transistors (OFETs), focusing on state-of-the-art solution-processable organic semiconductors, novel nano-scale dielectrics and metal inks, and their printing into large-area, multilayer, micro- and nano-scale device structures. This post forms part of the European Commision funded FP7 Printable Organic Large-Area Realisation of Intergrated Circuits (POLARIC) Project. It is expected that the person will register for a PhD degree at Imperial College London. To produce independent and original research involving organic field effect transistors and complimentary circuits, to submit project reports and publications to refereed journals, attend project meetings with other project partners, collaborate with other scientists involved in the POLARIC project (at Imperial College and with external partners, especially in Germany and Austria) and help with teaching and administration of the research group. The ability to print efficiently and reliably complex electronic and optoelectronic devices will have major impact on the commercial potential of organic electronics and associated fields impacting on light emitting displays, waveguides, solar cells and the like. The research carried out in this project will contribute to the design, fabrication, testing and optimisation of devices as part of a multi-national EU project on printing of fully-printable organic field-effect transistors and complementary circuits. In particular we are targeting (i) the design, fabrication, testing and optimisation of fully printable n- and p- type OFETs involving novel nanoparticle metal inks, (ii) the design, fabrication, testing and optimisation of low-voltage n- and p- type OFETs involving novel nano-scale dielectrics, (iii) the design, fabrication, testing and optimisation of organic complementary circuits based on these OFETs, (iv) the design, fabrication, testing and optimisation of these organic complementary circuits in novel architectures. Research Duties To take initiatives in the planning of research To design, fabricate, test and optimize p-type OFETs using novel organic semiconductors, dielectrics and metal inks To design, fabricate, test and optimize n-type OFETs using novel organic semiconductors, dielectrics and metal inks To design, fabricate, test and optimize n- and p- type OFETs in which one or more layers are printed. To design, fabricate, test and optimize n- and p- type OFETs in large-area arrays to achieve uniform performance. To design, fabricate, test and optimize organic complementary circuits in largearea arrays to achieve uniform performance. To design, fabricate, test and optimize n- and p- type OFETs printed in novel architectures. To design, fabricate, test and optimize organic complementary circuits printed in novel architectures.
