Project Description

Increased levels of indoor CO2 has been linked to occurrence of illnesses. Understanding and controlling common pollutants such as, CO2, indoors, can help to reduce the risk of indoor health concerns. The extraction of CO2 through effective carbon capturing technologies is considered to be one of the most promising options but needs to be thoroughly researched before it can be fully accepted as a long term solution.

Applications are invited for a fully-funded PhD studentship to develop an efficient and cheaper photonic-based CO2 gas sensor that underpin Electro-Mechanical technologies which can potentially replace the incumbent low-cost MOS gas sensors. The project scopes are to:

(1) design, fabrication and characterise Si/Ge waveguides operating at 4.26µm,
(2) design MEMS gas detectors with enhanced performance (e.g. detectivity, responsivity) and
(3) integrating the Si/Ge waveguides and infrared detector to realize the CO2 gas sensor.

The studentship holder will work closely with collaborators from A*STAR’s Institute of Microelectronics (IME), Singapore. IME is a research institute of Singapore’s Agency for Science, Technology and Research (A*STAR). It has 150+ team of scientists and engineers pool diverse experience and knowledge in key technologies such as integrated circuits and hardware AI, advanced packaging, advanced optics, sensors and actuators, embedded memory, and medtech capabilities, to serve technological needs for key and emerging markets driven by AI-enabled Internet-of-Things – consumer electronics, healthcare, automotive and industrial applications. Under this studentship, he/she will need to prepare and present results regularly, and will need to publish articles in high-profile journals, attend project progress meetings and international/domestic conferences.

The first year of the studentship is based within the Mechatronics Research Group and Nano Research Group in University of Southampton while the subsequent two years of the studentship will be based in IME, A*STAR, Singapore. The student is expected to return to University of Southampton in the fourth year to round up the project and to complete the thesis writing.

This project will best suit a graduate in Physics, Materials or Electronic & Electrical Engineering with a strong background in semiconductor materials and physics. Candidates from a Physics department are particularly welcome. An undergraduate degree with a 1st or 2:1 classification, or its international equivalent, is required.
