Research Fellow in Electron Microscopy of Organic Semiconductors

University of Leeds

Leeds, United Kingdom

Job posting number: #7081790 (Ref:EPSPE1045)

Posted: August 4, 2021

Job Description

Are you interested in advancing nanoscience for better optoelectronics? Would you like to develop cutting-edge electron microscopy to probe organic semiconductors? Are you interested in atomic to device-level materials characterisation challenges? Do you want to further your career in one of the UKs leading research intensive Universities?

Organic semiconductors encompass existing technologies from organic light emitting diodes (OLEDs) to emerging photovoltaics and transistors. Controlling the molecular-level ordering in small molecule and polymeric organic semiconductors is essential for driving forward exciting new photophysics in these materials. Connecting direct, nanoscale observations of changes in optical states with atomically precise descriptions of local, nanoscale structures remains largely unexplored. Increasingly, it is clear that structural and energetic disorder – for example, at defect structures, grain boundaries, and locally varying degrees of order in crystalline and amorphous organic semiconductors – substantially determines exciton and charge transport properties. 

As a Research Fellow in Electron Microscopy of Organic Semiconductors, you will take electron microscopy tools conventionally harnessed to explore defects and interfaces in metals, inorganic semiconductors, and ceramics and realise their full potential for organic semiconductors from isolated materials to multi-layer device structures. 

In the role, you will develop correlative low-dose scanning electron diffraction and ultrahigh energy resolution electron energy loss spectroscopy. You will also explore opportunities in cryogenic focused ion beam (FIB) techniques for cross-sectional and site-selective analysis of device structures. You will use microscopy facilities at the Leeds Electron Microscopy and Spectroscopy Centre (LEMAS) as well as at SuperSTEM, the EPSRC National Research Facility for Advanced Electron Microscopy and the national and international centres including the Electron Physical Sciences Imaging Centre at the Diamond Light Source.

You will join a wider team in advanced electron microscopy at Leeds and the Bragg Centre for Materials Research as well as a network of academic and industrial collaborators in the UK and internationally.
