The DFG Priority Program MemrisTec (SPP 2262) — “Memristive Devices Toward Smart Technical Systems,” has awarded Dr. Onur Toprak a MemrisTec Young Researcher Award for the Best Publication. The award recognizes Dr. Toprak’s exceptional contribution to the field of memristive devices and reinforces his standing as one of the program’s rising stars.
This honor adds to an already remarkable period in Dr. Toprak’s career. As a MemrisTec PhD student supervised by Prof. Dr. Catherine Dubourdieu at Helmholtz-Zentrum Berlin (HZB), he successfully defended his doctoral thesis at TU Berlin, achieving the outstanding grade of 1.0 (Magna cum Laude) — a distinction reflecting the excellence of his research within the MEMMEA project of the MemrisTec Priority Program.
The award-winning paper, titled “Amorphous Gallium-Oxide-Based Non-Filamentary Memristive Device with Highly Repeatable Multiple Resistance States,” was published in Advanced Electronic Materials. The work received an additional distinction by being selected for the front cover of the issue (designed by Laura Canils) — a clear recognition of its scientific impact and visual appeal.
Key highlights from the publication include:
- The development of an amorphous Gallium-oxide (a-GaOx) based memristive device that operates via a non-filamentary switching mechanism, distinguishing it from conventional filamentary memristors that often suffer from stochastic variability.
- Demonstration of highly repeatable multiple resistance states, a critical property for enabling multi-level memory storage and analog computing applications such as neuromorphic systems.
- A detailed analysis of the underlying interface-type switching behavior, providing valuable insight into how oxygen vacancy redistribution governs the smooth and reliable modulation of resistance.
- Strong endurance and retention characteristics, positioning the device as a promising candidate for next-generation in-memory and brain-inspired computing architectures.
The MemrisTec Priority Program aims to advance memristive technologies toward smart technical systems. Dr. Toprak’s award-winning contribution exemplifies the program’s mission — bridging fundamental materials science with practical, application-oriented device engineering.
Congratulations to Dr. Onur Toprak on this well-deserved recognition! All the best for your future!
