Orientation

Why is the scientific problem of interest at all?

 Conjugated polymers are carbon-based materials with extended pi-electron orbitals that can support both charged and neutral excitations. They are characterised by a rich photophysics revolving around the formation, diffusion, radiative or non-radiative decay, as well as dissociation and/or endothermic regeneration of excitonic species (bound hole-electron pairs – 04-1 eV binding energy).

How

How is the research going to shed light on the given problem?.

A precious tool to investigate such phenomena, that also underpin the exploitation of these materials in polymer light-emitting (PLEDs) and photovoltaic diodes, PVDs, field-effect transistors, as well as in FETs and light-emitting transistors (LETs), is time-resolved photoluminescence spectroscopy.

 

 

What

What is the specific thing that the student will do, and how does it fit inside the overall project?

This project will provide an opportunity to gain expertise in the area of conjugated, polymeric semiconductors which is attracting a burgeoning interest, world-wide, in both condensed matter physics and, especially, Optoelectronics.
