Light emitting two-dimensional materials for silicon emitters
Silicon photonics has been widely recognized as the potential technology to achieve broadband, high-density, high-speed data interconnections for next generation computing. The progress achieved in recent years in this field has been very exciting. However, an on-chip silicon light source at low-cost still remains challenging, as silicon itself does not emit light efficiently. Two-dimensional (2D) materials that were spawned out of the graphene revolution can address this challenge. This family of materials exhibit remarkable properties, including excellent electrical conduction and efficient light emission.
The aim of this project is to develop silicon light-emitting diodes (LEDs) and lasers by integrating 2D materials with silicon nanocavities. The student will work alongside research assistants, and UK and international collaborators to examine the light-emitting properties of suitable 2D materials that are both optically and electrically pumped. The student will also be involved in the design of passive and active devices using computer modelling, fabrication and characterisation of devices in our state-of-the-art clean room and optics laboratories.
We are looking for an enthusiastic candidate with a background in photonics, electronics, physics or material science to take on this project. The PhD studentship will be undertaken within the Department of Physics at the University of York, starting before October 2019. The three-year studentship provides a yearly stipend (£14,777 for 2018-2019). The studentship also covers fees for UK students. Informal inquiries can be made to Dr Y Wang ([Email Address Removed]) with a copy of your curriculum vitae and a cover letter.
