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. |
