Job Description

Resistive switching memory devices based on metal oxides (ReRAM) are a promising candidate for future non-volatile memory and neuromorphic computing technologies and recently entered the market as eNVM. However, these devices often exhibit a metastable resistance state shortly after programming, which can evolve over time before stabilizing. At our Peter Grünberg Institute - Electronic Materials (PGI-7), we work on understanding the physical origin of this metastability is key to improving device reliability and performance.

Your Job:

In this Master’s thesis, you will investigate the impact of different programming algorithms on the stability of resistance states using a sophisticated 3D Kinetic Monte Carlo (KMC) model. The aim is to explain experimentally observed metastable behavior and to identify strategies to minimize or control such effects. The simulations are performed on the JURECA high-performance computing cluster, and the work will be carried out in close collaboration with experienced researchers at PGI-7. Your tasks include:



Applying a 3D KMC simulation framework to model resistive switching in metal oxide ReRAM Investigating the effect of different programming schemes on state stability Analyzing and interpreting the simulation results to explain metastable behavior Identifying potential optimization strategies for improved device performance
