PhD Microstructured ultra-thin light emitting array technologies

BC-50 PhD Microstructured, ultra-thin light emitting array technologies

Contract type: Full-time

Tyndall National Institute at University College, Cork wishes to appoint a candidate to a PhD Studentship.

Light-emitting diodes (LEDs) using GaN-based semiconductors are transforming illumination. In addition being the most efficient technology, they open the door to research and development into “more-than-illumination” concepts, such as controlled colour temperature lighting, structured illumination, integrated visible light communication lighting systems and microdisplays.  These approaches benefit from novel addressable arrays of microLEDs, as opposed to simple large area devices. Tyndall is partnering in an Europe wide collaboration, Microprince, to integrate semiconductor device arrays in larger systems using a new heterogeneous integration technique.  Tyndall will develop the new energy-efficient light sources, and particularly new ways to integrate these light sources into addressable arrays, this latter area in conjunction with X-Celeprint who have developed equipment to take tiny “stamps” of expensive semiconductor devices of only a few microns thickness, and print them onto larger area target substrates of a different material. We will initially target multi-coloured displays which can be assembled while allowing recycling of special semiconductor substrates that normally are too expensive for commercial use, but which can give significant performance benefits over current state-of-the-art products.  We target extension of the wavelengths GaN LEDs can cover in practice, and ultra-thin compact laser diodes. 

As a result we have an opportunity for a PhD student to join our dynamic project team working across the growth, fabrication and integration of optoelectronic devices. The successful candidate will be involved in all the development steps, including device design, semiconductor wafer growth, device fabrication and device validation, all using the state-of-the-art laboratories at Tyndall.  Scientific methods will be used throughout the project to improve our understanding of the mechanisms that govern the device and ultimately, the system performance.

Key Duties and Responsibilities

  • Applications are invited from ambitious, highly motivated students who have a first class degree in physics, engineering or a similar discipline.
  • A master’s degree in semiconductor physics or optoelectronics is an advantage.
  • The student should be familiar with the physics of semiconductor light generation.
