We are recruiting a PhD student in multi-scale simulations to model novel thermal atomic layer etching (ALE) chemistries. The position is supported by a Semiconductor Research Corporation (SRC) project further supported by Intel.

The overall aim of this project is to explore the chemistry of self-limiting thermal atomic layer etching (tALE) which is being deployed for precise, controlled etching of a range of materials with a view to applying this in the fabrication of next generation semiconductor devices where complex 3D structure and ultra thin films are required. While there has been some significant advances in thermal ALE [doi:10.1021/acs.accounts.0c00084, doi:10.1016/j.pnsc.2018.11.003, doi:10.1116/6.0000894] and the MMD group at Tyndall has pioneered the atomistic simulation of thermal ALE of metal oxides and metals [doi:10.1021/acs.chemmater.8b01930, https://chemrxiv.org/engage/chemrxiv/article-details/6183ac019b583aca9deb1f67, doi:10.1116/6.0000804, https://pure.ulster.ac.uk/ws/files/85689489/ALE_Manuscript.pdf], there are still many open questions. This project aims to understand the role of surface orientation, surface defects and terminations, find alternatives to HF and develop libraries of tALE process chemistries.

A background chemistry/materials/sold state physics, whereby previous experience with programming and machine learning will be a significant benefit. Ideally, some exposure to first principles simulations for materials discovery or other atomistic simulations approaches would be part of a candidate’s background.

As part of this role the candidate will take training and development opportunities at Tyndall and UCC, as well as relevant postgraduate and undergraduate modules to drive their wider training and development. Please see postgraduate-research and https://www.ucc.ie/en/study/postgrad/.

The annual stipend is €22,000 pa, tax free. In addition, yearly University academic fees will paid by the Tyndall National Institute.

Informal enquiries can be made in confidence to Michael Nolan at [email protected].

The closing date for applications is 29th March,  2024.
