About the Project

The University of Bath is inviting applications for the following PhD project under the supervision of Dr Sara Dale in the Department of Physics.

Funding is available to candidates who qualify for Home fee status. Following the UK’s departure from the European Union, the rules governing fee status have changed and, therefore, candidates from the EU/EEA are advised to check their eligibility before applying. Please see the Funding Eligibility section below for more information.

2D materials have seen an explosion of research since the isolation of graphene in 2004. Transition metal dichalcogenides are one class of 2D materials which have the formula MX2 where M is the transition metal and X is the chalcogen (S, Se or Te). These materials have a wide variety of electronic properties including semiconducting, metallic, charge density wave and superconductivity.

Controlling the electronic properties of 2D materials can take many forms including chemical doping, intercalation of molecules in between layers and electric field doping. The latter of these techniques allows precise control of the electronic state of the 2D material for example a semiconducting insulating 2D material can be doped into the conducting and even superconducting state.

This PhD is concerned with fabricating ionic liquid field effect transistors from 2D materials and using the chemistry of the ionic liquid to manipulate the electronic properties of the material. The PhD candidate will have access to clean room facilities and receive training in lithographic fabrication techniques. This is an interdisciplinary project between physics and chemistry and the student will receive training in all aspects of the work.

Candidate Requirements:

Applicants should hold, or expect to receive, a First Class or good Upper Second Class Honours degree (or the equivalent). A master’s level qualification would also be advantageous.

Non-UK applicants must meet our English language entry requirement.

Enquiries and Applications:

Informal enquiries are welcomed and should be directed to Dr Sara Dale ([Email Address Removed]).

Formal applications should be made via the University of Bath’s online application form for a PhD in Physics.

More information about applying for a PhD at Bath may be found on our website.

Funding Eligibility:

In order to be considered, you must qualify as a Home student. 

In most cases, EU citizens will qualify for Home fee status if they start their PhD studies before 1 August 2021.

From 1 August 2021, the criteria under which fee status is assessed will change and EU/EEA citizens who live outside the UK are unlikely to be eligible for Home fees and funding.

In determining Home student status, we follow the UK government’s fee regulations and guidance which, when available, will be set out by the UK Council for International Student Affairs (UKCISA) on their website. Although not yet confirmed by UKCISA, we expect that the main categories of students generally eligible for Home fee status for courses commencing on or after 1 August 2021 will be:

  • UK nationals (who have lived in the UK, EU, EEA or Switzerland continuously for 3 years prior to commencing the PhD)
  • Irish nationals (who have lived in the UK or Ireland continuously for 3 years prior to commencing the PhD)
  • EU/EEA applicants with settled or pre-settled status in the UK under the EU Settlement Scheme (who have lived in the UK, EU, EEA, Switzerland or Gibraltar continuously for 3 years prior to commencing the PhD)
  • Applicants with indefinite leave to enter/remain in the UK (who have been resident in the UK continuously for 3 years prior to commencing the PhD)

EU/EEA citizens who live outside the UK are unlikely to be eligible for Home fees and funding.

Additional information may be found on our fee status guidance webpage, on the GOV.UK website and on the UKCISA website

Start date:

To be agreed with Dr Sara Dale. The latest possible start date is 4 October 2021.


Applications may close earlier than the advertised deadline if a suitable candidate is found; therefore, early application is strongly recommended.

Funding Notes

A studentship is available covering tuition fees at the Home level and a stipend (£15,285 p.a in 2020/21, rising to £15,609 p.a. in 2021/22) for up to 4 years. Eligibility is restricted to applicants who qualify for Home fee status (see above).
