3. University of Surrey (USUR)

Description and main tasks

The University of Surrey (USUR) was established in 1966 by Royal Charter. It is a global university with a world-class research profile and an enterprising spirit. In 2002 it won Queen's Anniversary Prize for Higher & Further Education for its internationally renowned research and development on optoelectronic devices and ion beam applications. The Advanced Technology Institute (ATI), as part of the university, houses some 160 multidisciplinary researchers and many of the major facilities for production of carbon nanotechnology and the fabrication and characterization of electronic devices, including an ion beam centre, a microfabrication clean-room, a nanofabrication/nanoprobe laboratory, an ultra-fast laser laboratory and a plasma laboratory.

Expertise related to the project

USUR will be involved in the materials processing and fabrication of OPVs, PPV, OTFT and OLED devices by a variety of lab-scale (spin coating, slot-die, gravure printing, casting, inkjet printing) fabrication techniques, will assess the developed protocols for the optimization of lab-scale processes, and will contribute to modeling of integrated nanomaterial properties, their integration into devices and their subsequent effect on electrical and optical device properties across multi-scale dimensions. Characterization will be undertaken using optical (PL, EQE, Solar simulator) and electrical techniques for device characterization, and physical characterization (AFM, KPFM, STS, SEM, TEM, Contact Angle) for nanomaterials analysis. In modelling we will use VASP to determine energy minimized structure-property relationship of organometallic perovskites for PPVs paying attention to electronic band structure (with spin-orbit coupling) and band occupancy arising from density of states calculations. We will explore how different atom substitutions affect the nature (direct/indirect) band gap and the formation of defects and determine the relative energy scales (band offsets and alignments) and relate to electrical transport data.
