Project

MODEST: "Modelling Organic Devices, Excitation and Spin Transport"

Organic materials combine the processing and mechanical advantages of plastics with the electrical properties of semiconductors and can pave the way towards environmentally sustainable electronics. Organic light emitting diodes already grab a big piece of the electronic displays pie and have a huge growth potential. Organic photovoltaics are still lagging behind but their potential has not been explored fully yet. OLEDs convert electricity, injected charge carriers, into light. The operation of organic solar cells involves the reverse process, converting absorbed light, excitons, into electricity. The MODEST project will help unlocking important information on fundamental structure-property relationships in organic and molecular electronic materials. Initial efforts will focus on the transport and dynamic interactions of charged and neutral excitations and how these affect device performance. It will also concentrate on developing device scale models to fully explore the optoelectronic properties in silico and guide material design.

CV

Stavros studied Physics at the University of Ioannina, Greece, and received his PhD in Physics from Lancaster University, UK. His thesis dealt with spin-polarised quantum transport in carbon nanotubes. During his postdoctoral work at the University of Bath, UK (2005-2008), he turned his attention to modelling organic semiconductors. He subsequently moved to the University of Mons, Belgium, where he was later awarded a Postdoctoral Fellowship from FNRS (2009-2011). His last two appointments were in experimental Physics groups. In 2012 he joined the Optoelectronics group at Cavendish Laboratory in Cambridge, UK, and in 2015 he moved to the University of Bayreuth, Germany. He has been a visiting researcher at Los Alamos National Labs, US, and at the University of Bayreuth.

His research interests lie in the area of organic and molecular electronics. He is engaged in studying fundamental transport phenomena in nanostructures, in particular the dynamics of charges, spins and excitons in disordered electroactive functional materials.
