Funded PhD - Diode Materials [PP-05]

Title : PhD: Characterisation of high efficiency ultra-violet light emitting diode materials (Reference number PP – 05)

A funded PhD position is currently available to prepare and characterise wide bandgap group III nitride semiconductor materials for application in ultra violet light emitting diodes (UVLEDs).

UVLEDs have application in a wide variety of areas, including medical diagnostics and treatments, scientific analysis and sterilisation. However to realised these higher efficiencies are needed so that higher brightness LEDs can be made. In this project a new concept: that of using AlInN alloys will be investigated. Work in this area is in its infancy, and its application to the UV is essentially unexplored, leading to the scope for high impact research.

In particular there is the largest bandgap difference known for a semiconductor alloy system which leads to extreme effects to be explored by spectroscopy, such as photoluminescence, where a brand new dedicated state of the art laboratory will be available. The student will also be expected to participate in the materials growth using a metalorganic vapour phase epitaxy, using a recently installed new reactor. By assessing the light emitting properties and comparing to the semiconductor growth condition improved designs for the active region of the LED will be made and incorporated into devices. Assessment of the LEDs and comparing with the photoluminescence will be another key aspect of the programme.

The student appointment is fully funded for four years and is part of a Science Foundation Ireland research programme funded at Tyndall National Institute.

Qualifications & Person Specification:

The successful candidate will have a strong background in Physics or Electronic Engineering at undergraduate or masters level with particular interests in Semiconductors, Solid State Physics and/or Optical Properties of materials.
