Jülich: Master Thesis - Modeling sub-ns Switching of Bridge-Type Phase Change Memories

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)
