Alex Shluger: Modelling diffusion of atoms in metal interconnects in devices
Please note that owing to funding restrictions beyond the supervisors’ control, this PhD studentship is open only to British citizenships or to EU citizens with UK (pre-)settled status eligible for home fees.
As the dimensions of nanodevices continue to shrink and approach 2 nm, the complexity of the manufacturing process increases. Metal interconnects that link different parts of integrated circuits are the key factor in determining device performance, speed, and power efficiency. This PhD project aims to improve efficiency of power-hungry AI devices through better understanding of the mechanisms of their degradation. It will combine density functional theory simulations, development and applications of machine learning potentials and molecular dynamics simulations to provide atomistic-level understanding of the diffusion properties of metal atoms in semiconductor/metal heterostructures. These results will be used to study the movement of metal atoms under the influence of electric field in device settings and to model electromigration and growth of voids leading to interconnect failure (see figure below).
We are looking for a highly motivated candidate with a top-level MSci degree or equivalent in Chemistry, Physics, or Materials. Undergraduate knowledge of Quantum Physics/Chemistry and Solid-State Physics/Chemistry is essential. You should enjoy coding and be keen to push the boundaries of materials modelling in close collaboration with industrial partners. The PhD training and research will be carried out in the group of Prof. Alexander Shluger in the Department of Physics and Astronomy, UCL and within the vibrant environment of the London Thomas Young Centre. Good writing and presentation skills and the ability to actively collaborate in a multidisciplinary team of theorists, experimentalists and engineers is essential.
Applications should be made to UCL by the 1st of January 2026 and will be considered as soon as possible. The expected start date can be as soon as possible or in September/October 2026. The award will cover fees and an annual stipend at the EPSRC-DTP rate. For further information on this PhD position please contact Prof. Alexander Shluger a.shluger@ucl.ac.uk .
