About the Project

The EPSRC Centre for Doctoral Training (CDT) in Renewable Energy Northeast Universities (ReNU)is a collaborative doctoral training programme run by the Universities of Northumbria, Newcastle and Durham. In addition to undertaking an individual scientific research project at one of the three partner Universities, doctoral candidates will engage with added value training opportunities, for example in business, innovation and internationalisation through a 4-year training programme that has been designed to maximise the benefits of a cohort approach to doctoral training. The start date is 1st October 2023.

The aim of this project is to develop tunable metasurfaces that can be integrated with photovoltaic devices, detectors and sensors for enhanced performance. Specifically, tunable metamaterials for efficient and band selective absorption of electromagnetic devices in infrared and terahertz bands will be researched. A particular interest is to research radiation-based energy transfer and recovery.

We will provide high-quality training for conducting scientific research to ensure the student develop skills in electromagnetic metamaterials, device fabrication, photovoltaics, and material physics. The skills can be translated into exciting opportunities in applications including renewable energy system development and metamaterial design for optoelectronic devices. These applications are part of the industrially funded projects at the department, and this project is complementary to these efforts. Outcomes of this project and the obtained skills can be further developed in collaboration with the industrial partners.

Efficient absorption of photons is a fundamental first step that sets the performance of photovoltaic generators. Conventionally, the availability of materials restricts the efficiency of absorption and determines the specific bands. Reliance of specific materials for absorption can be overcome using metasurfaces that can be integrated with photovoltaic devices to enable absorption of electromagnetic waves in unconventional bands to complement the current devices. In this research, perfect absorbers with tunable absorption bands will be realised for various applications in a wide spectrum spanning from microwave to photonic bands. Whilst the particular focus will be on photovoltaics, wider applications in detectors and sensors will also be explored.

Academic Enquiries

Funding Information

Home and International students (inc. EU) are welcome to apply. The studentship is available to Home and International (including EU) students and includes a full stipend at UKRI rates (for 2022/23 full-time study this is £17,668 per year) and full tuition fees. Studentships are also available for applicants who wish to study on a part-time basis (0.6 FTE, stipend £10,600 per year and full tuition fees) in combination with work or personal responsibilities). 

Please also see further advice below of additional costs that may apply to international applicants.

Eligibility Requirements:

  • Academic excellence of the proposed student i.e. 2:1 (or equivalent GPA from non-UK universities [preference for 1st class honours]); or a Masters (preference for Merit or above); or APEL evidence of substantial practitioner achievement.
  • Appropriate IELTS score, if required.
  • Applicants cannot apply for this funding if they are already a PhD holder or if currently engaged in Doctoral study at Northumbria or elsewhere.

Please note: to be classed as a Home student, candidates must meet the following criteria:

  • Be a UK National (meeting residency requirements), or
  • have settled status, or
  • have pre-settled status (meeting residency requirements), or
  • have indefinite leave to remain or enter.

If a candidate does not meet the criteria above, they would be classed as an International student. Applicants will need to be in the UK and fully enrolled before stipend payments can commence, and be aware of the following additional costs that may be incurred, as these are not covered by the studentship.

  • Immigration Health Surcharge https://www.gov.uk/healthcare-immigration-application
  • If you need to apply for a Student Visa to enter the UK, please refer to the information on https://www.gov.uk/student-visa. It is important that you read this information very carefully as it is your responsibility to ensure that you hold the correct funds required for your visa application otherwise your visa may be refused.
  • Check what COVID-19 tests you need to take and the quarantine rules for travel to England https://www.gov.uk/guidance/travel-to-england-from-another-country-during-coronavirus-covid-19
  • Costs associated with English Language requirements which may be required for students not having completed a first degree in English, will not be borne by the university. Please see individual adverts for further details of the English Language requirements for the university you are applying to.

How to Apply
