How to apply

Please note – the CDT will be represented at Cardiff University Postgraduate Open Day, 17 March 2021.

Our PhD programme has a single intake in October, with up to 14 places available in 2021 and similar numbers in 2022 and 2023.

We welcome applications from individuals holding or expecting a good degree in physics, electronic or electrical engineering (first or 2:1) with a genuine interest in compound semiconductors and enthusiasm for the group approach. Applicants with a lower second class degree (2:2) may be considered if they have a good result at Masters-level study (merit or distinction) and/or other relevant qualifications or industry experience which demonstrates their scientific or engineering research capability.

Applicants whose first language is not English are normally expected to meet the minimum requirements of Cardiff University, which is currently an IELTS (Academic) of 6.5 with a 5.5 in each sub-score.  

Applications for the 2021 intake will be considered in two tranches, with deadlines as follows:

•            10 January 2021 to be interviewed in early February  

•            6 April 2021 to be interviewed in late April

If places remain after the April round, there will be a final round in late June.

We recommend you apply as soon as possible to receive full consideration. 


Interviews are required, though these may be in person or virtual depending on your location and the current COVID-19 situation.  We will pay reasonable expenses for attendance at interview. Details will be provided in your invitation.   


You must provide two recent references, dated within the last six months, that address your capability for PhD study, at least one of which should be an academic referee. These should be uploaded not later than the application deadline, where possible, but before the interview date in all cases. At least one positive reference is required for us to make you an offer.   


Our studentships are available to Home and International (which now includes EU/EEA) applicants, however there is a cap on the number of international studentships that can be awarded.  The studentship pays the UKRI Home tuition fee, so international students may have to pay the difference between that fee and the University’s international tuition fee.  See the fee information for Cardiff, Manchester, Sheffield and UCL for more details. We will update applicants when further information becomes available.  In the meantime, information on eligibility can be found on the UKRI website

Please see full details of the programme and online application form via the Cardiff University website.    

If you have any queries, please do not hesitate to get in touch with us at or by telephone on 029 2251 1593 (phone option is not currently available due to COVID-19 campus closure).
