  Faculty of Science URSA PhD Project: Understanding and engineering the electronic phases in graphene nanoribbons


   Department of Physics

  ,  Wednesday, December 11, 2024  Competition Funded PhD Project (Students Worldwide)

About the Project

This project is one of a number that are in competition for funding from the University of Bath URSA competition, for entry in September 2025.

Supervisory Team:

Dr Michele Pizzochero & Dr Marcin Mucha-Kruczynski

Overview of the Research:

Graphene nanoribbons (GNRs) are a fascinating class of quasi-one-dimensional semiconductors consisting of few-nanometer-wide strips of hexagonally-bonded carbon atoms. Thanks to their tunable band gaps, atomic thinness, and facile integration into short-channel field effect transistors, GNRs are a promising platform for post-silicon electronic devices in the ultimate limit of miniaturization.

Recent advancements in fabrication techniques allow for the atomically precise synthesis of GNRs with diverse edge geometries, widths, and intricate nanoarchitectures. This progress paves the way for the realization of all-carbon nanocircuits. Devising effective routes to control the electronic structure of GNRs is of crucial importance to advance the development of such technologies.

Building on our previous works (see References), this computational project seeks to understand and manipulate the electronic structure of graphene nanoribbons. Using ab initio density-functional theory and model Hamiltonian calculations, the PhD student will identify viable strategies to control the electronic and magnetic functionalities of GNRs via external stimuli, e.g., defect-mediated engineering, lattice deformations, as well as integration into lateral and vertical heterostructures. Specific research directions will be tailored to the background, interests, and aspirations of the successful candidate.

Candidate Requirements:

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

Applicants should have basic knowledge of condensed matter physics and electronic structure theory.

Desirable criteria:

• A master’s level qualification

• Experience with atomistic simulations (e.g., DFT, MD)

• Programming skills

• Experience with high-performance computing

Non-UK applicants must meet the programme’s English language requirement prior to the closing date of this advert.

Enquiries and Applications:

Informal enquiries are encouraged and should be directed to supervisor Dr Michele Pizzochero,

Formal applications should be submitted via the University of Bath’s online application form for a PhD in Physics prior to the closing date of this advert.

IMPORTANT:

When completing the application form:

1.      In the Funding your studies section, select ‘University of Bath URSA’ as the studentship for which you are applying.

2.      In the Your PhD project section, quote the project title of this project and the name of the lead supervisor in the appropriate boxes. 

Failure to complete these two steps will cause delays in processing your application and may cause you to miss the deadline.

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

Equality, Diversity and Inclusion:

We value a diverse research environment and aim to be an inclusive university, where difference is celebrated and respected. We welcome and encourage applications from under-represented groups.

If you have circumstances that you feel we should be aware of that have affected your educational attainment, then please feel free to tell us about it in your application form. The best way to do this is a short paragraph at the end of your personal statement.
