PhD in the Next Generation of Organic LEDs

Summary:

Applications are invited for a PhD in Organic Electronics with particular emphasis on organic light-emitting diodes materials & devices.

Project Description:

Organic light-emitting diodes (OLEDs), as one of the leaders of the display revolution over the past decade, have shown huge advantages over other popular technologies, such as Liquid Crystal Displays (LCDs), as they provide better contrast ratios, wider viewing-angles, can be mechanically flexible and consume less power. Current commercial products utilizing OLED technology includes bendable smartphones, rollable TVs and smart vision VR glasses. Yet, this fascinating technology still faces big challenges regarding energy conversion, operational lifetime, and colour purity.

The primary objective of this project is to develop state-of-the-art OLEDs for displays applications. You will investigate the fundamental understanding of exciton dynamics in electrically pumped devices, giving the foundations to design and fabricate OLEDs that show higher energy efficiencies and longer operational lifetimes than existing commercial ones. Importantly, studies focusing on how to suppress degradation mechanisms via device engineering will be developed to achieve the ambitious goal.

The recruited PhD student will work in a dynamic, cross-disciplinary, and supportive research environment. You will be trained in one of the world's leading centres of excellence conducting research in next generation semiconductor materials and devices. Training will include device fabrication via thermal evaporation under industrial standards, device characterization using a range of advanced techniques such as time-resolved electro-optical spectroscopy and fundamental photophysics of semiconductors.

About the Research Group:

The Semiconductor Materials & Devices (SMD) group is internationally leading the design, fabrication and engineering of both electronic and opto-electronic devices. The group benefits from extensive cleanroom facilities including; state-of-the-art epitaxy, lithography and device manufacturing tools, ultra-high resolution electron microscopy, and numerous suites of tools for opto-electronic and electronic device design and characterisation.

Academic Requirements:

Applicants should have, or expect to achieve, at least a 2:1 Bachelors/Masters Honours degree in Electronic Engineering, Physics or Chemistry a closely related discipline. The student should have skills in semiconductors, Optoelectronics, or Organic Electronics. The studentship is available to home applicants only, and will ideally start in October 2023 with start dates flexible on agreement.
