PH-13 PhD: “Next generation displays for augmented reality”. Supported by Meta
Contract: Full Time/Fixed Term
The ability to form displays comprised of microscale light emitting diodes (LEDs), where the LED lateral dimensions are around 2um, is central to the realisation of Augmented Reality Head-Mounted Displays. Such head-mounted displays, which augment our surroundings, will open the door to a vast range of new applications in areas such as: surgery, manufacturing, training, entertainment and education.
The current research challenge in terms of the practical realisation of such displays, is the properties of the semiconductor/oxide interface at, or near, the periphery of the light emitting diodes. The semiconductor materials which are used for light emission are called compound semiconductors and are typically comprised of two or three elements from groups III and V of the periodic table (e.g., GaAs, InGaP, GaN, InGaN). As the lateral dimensions of the LEDs drop below around 10um, which is required for a high-resolution display, crystalline defects at the periphery of the device, or within the surrounding passivation oxide, can play an increasing role, and act as non-radiative recombination centres, reducing the internal quantum efficiency. The problem is particularly challenging in the case of the red microLED, typically formed using the compound semiconductor InGaP. The ability to understand, control and passivate these non-radiative defects is at the heart of 4 PhD positions supported by Meta.
The 4 PhD positions will cover the following research areas:
The PhD positions are fully supported by Meta and will help to inform Meta's interests in heterogeneous systems and improvement in the internal quantum efficiency of microLEDs.
