A Doctoral Researcher/Project Researcher in atomistic simulations of phase-change memory materials
In the scenic and historically-rich Turku region of southwestern Finland, the University of Turku is a world-class multidisciplinary research university, hosting a vibrant community of 25,000 students and employees from over 100 different countries. As one of the leading universities in Finland, the University of Turku offers study and research opportunities in eight different Faculties. The Department of Mechanical and Materials Engineering, at the Faculty of Technology, brings together experts in physics, chemistry, and engineering in a drive towards innovative materials engineering for future groundbreaking technologies and key societal challenges.
We are now looking for a Doctoral Researcher or a Project Researcher in the field of computational materials modelling. You will be working on a project funded by the Research Council of Finland https://research.fi/en/results/funding/81517, and in this position you will have a chance to push the boundaries of knowledge and, hence, make an impact on semiconductor memory technology by applying tools from computer simulations and machine learning. The position is fixed-term and the starting time is 01.06.2025, or as soon as possible thereafter, based on mutual agreement. The contract duration will be three (3) years from the starting date, if a Doctoral Researcher is hired for the position. In the case that a Project Researcher is hired for the position, the duration of the initial contract is six (6) months, i.e., until the candidate is expected to have the doctoral study rights. The work will be supervised by the Academy Research Fellow Dr Konstantinos Konstantinou.
About the research project
Phase-change memory devices, based on Ge-Sb-Te alloys, are part of some commercial non-volatile solid-state drives, and they are also promising candidates for neuromorphic and in-memory computing applications. As an innovative solution, chalcogenide phase-change materials have been proposed for spaceborne solid-state memory modules because of their non-volatile, reconfigurable, fast-switching, and space radiation tolerant capabilities. In this project, the aim is to develop a complete framework for ion-irradiation simulations in phase-change memory materials in order to build a comprehensive theoretical perspective on the effects of radiation damage on these materials, and therefore facilitate their design for integration in environments where exposure to radiation is a factor. The potential candidate will perform large-scale machine-learned driven molecular-dynamics simulations of ion irradiation in phase-change materials, to obtain realistic models and evaluate the resilience of the irradiation-induced effects. The impact of the electronic excitations will be explored by computing electronic stopping power in the glassy and crystalline states of phase-change materials with time-dependent density-functional theory calculations. The research will be carried out with international collaborators from the UK and Spain.
The Doctoral thesis topic and the relevant research tasks can be specified according to the candidate’s own interests around these themes. In addition, the researcher could be involved in the other research activities of the supervisor. The doctoral dissertation will be conducted within the PhD program at the University of Turku https://www.utu.fi/en/research/utugs.
Who we are looking for
Qualifications, experience and ambitions
We welcome motivated applicants with a degree in physics, chemistry, or materials science & engineering. We seek candidates who are passionate about computational materials modelling and are eager to push the boundaries of semiconductor memory technologies. This project requires a broad understanding of the atomic, dynamical and electronic properties of materials, as well as techniques for analysis of simulations. Prior experience with atomistic simulations is a bonus. The position requires an active approach, rigorousness, creative thinking and cooperation skills. Fluent oral and written communication skills in English are required. We further value willingness to travel, teach and mentor younger students, collaborate and communicate science. In principle, we value equality and diversity in our work community and encourage qualified applicants, regardless of background, to apply for our open positions.
For this position, one or more of the following scientific knowledge and skills will be appreciated:
- Atomic, electronic and dynamical properties of materials
- Computer simulations of radiation damage in crystalline and amorphous materials
- Molecular-dynamics simulations
- Density functional theory (DFT) calculations
- Time-dependent DFT calculations
- Atomistic simulations packages such as LAMMPS, DL_POLY, CP2K, and SIESTA
- Machine-learned (ML) interatomic potentials, such as DeepMD, GAP, and ACE
- Phase-change memory materials and semiconductor memory technologies
The qualification requirements of the relevant positions are stated in the University of Turku Rules of Procedure. A person selected for the post of Doctoral Researcher/Project Researcher is required to have a higher university degree. In addition, when acquiring their degree or otherwise, they are required to have demonstrated the ability and motivation to undertake postgraduate studies and the capacity to complete a doctoral degree in accordance with the research plan. The selected student will need to apply for the right to pursue a doctoral degree (in the next possible application period) at the University of Turku. Thus, please check the student information and application criteria https://www.utu.fi/en/research/utugs/dpt/admission (pay attention to mandatory skill level in English). It is noted that before obtaining the study right for a Doctoral Program, the job title will be Project Researcher. Candidates who will graduate soon (MSc students) are also encouraged to apply. In these cases, the title of the selected person will be Research Assistant and the duration of the initial contract is six (6) months, which then will be upgraded to the correct title and with the appropriate change in salary, if the relevant degree is obtained within these 6 months.
