Job Description

Phase change memories (PCM) are an interesting candidate for future non-volatile memory and neuromorphic computing technologies. For the latter application, the resistance should be changed gradually at fast speed. At the Peter Grünberg Institute - Elektronische Materialien (PGI-7), we recently showed that PCM materials can be switched electrically in the sub-nanosecond regime with a record of 50 ps. In this regime, gradual RESET switching becomes feasible, which is not well understood yet.

Your Job:

In this Master’s thesis, you will model bridge-type PCM devices in the sub-nanosecond regime. The aim is to explain experimentally observed dynamical behavior based on continuum simulation models. The work will be carried out in close collaboration with experienced researchers at PGI-7. Your tasks include:



Applying a continuum simulation framework to model PCM devices Investigating the effect of different material properties on the switching dynamics Analyzing and interpreting the simulation results to explain the switching dynamics Identifying potential optimization strategies for different application use cases

Your Profile:

Enrolled in a Master’s program in physics, materials science, electrical engineering or a related discipline Solid background in solid-state physics and/or semiconductor devices is helpful Basic programming skills (e.g. Python or MATLAB); prior simulation experience is an advantage Interest in nanoscale transport phenomena and physical modeling Independent, structured, and motivated working style Good command of English (written and spoken)

Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We support you in your work with:



A research topic with strong relevance for future memory technologies Work with a well-established FEM simulation tool Close supervision and integration into a highly motivated, interdisciplinary team Opportunity to contribute to ongoing industry-related research Flexible working conditions (start date, working hours, home office options)

In addition to exciting tasks and a collaborative working atmosphere in Jülich, we have a lot more to offer: https://go.fzj.de/benefits



The position is initially for a fixed term of up to 12 months.



We welcome applications from people with diverse backgrounds, e.g. in terms of age, gender, disability, sexual orientation / identity, and social, ethnic and religious origin. A diverse and inclusive working environment with equal opportunities in which everyone can realize their potential is important to us.
