Conducting research for a changing society: This is what drives us at Forschungszentrum Jülich. As a member of the Helmholtz Association, we aim to tackle the grand societal challenges of our timeconduct researchthe possibilities of a digitized society, a climate-friendly energy system,a resource-efficient economy. Work together with around 6,800 employees in one of Europe’s biggest research centreshelp us to shape change!
The Peter Grünberg Institute – Electronic Materials (PGI–7) – is working for the development of memristive devicestheir utilization in new neuromorphic computing concepts by means of co-integration with CMOS-blocks. For future realization of cognitive hardware for self-learning systems, especially energy efficient memristive devicescircuit designs are required. The study will be part of the BMBF-funded project NEUROTEC (fz-juelich.de/pgi/DE/Forschung/NEUROTEC). Memristive devices inherently combine the ability to processto store data in the same physical place, which eliminates the need for large data movement. Together with their two-terminal structurepossibility for low power consumption, they are seen as one of the most promising technologies for accelerating future computers. However, challenges such as resistanceswitching variability hinder large scale integration. Parallel to the optimization of these switching properties by means of composition of materials, stack order etc., small scale test vehicles, i.e. silicon chips with predefined transistors, are preparedtested. Back-end-of-line integration techniques such as deposition via atomic layer depositionnano-lithography are involved. The integrated switches should be compatible to the connected silicon transistors, enabling the demonstration of the expected enhancement principles by integration with foundry-manufactured NC-chips provided by the NEUROTEC consortium.

PhD Position in OptimizationIntegration of Memristive Switches for Neuromorphic Computing Applications
You will fabricate nano-structured Valence Change Mechanism memresistive devices using technologically promising materials such as HfO2Ta2O5 sandwichedPtTiN on one sideTiW on the other side. The different oxides are to be grown using atomic layer deposition (ALD).
You will perform the electrical characterization of the devices. Current-voltage measurements should be carried out in sweeppulse mode to explore the resistive switching as well as analog features, which are essential for most use cases in neuromorphic circuits.
The target is to maximize the yieldthe uniformity of the switching devices, so the neuromorphic principles can be reliably demonstrated on the silicon transistor chip. The required tests therefore focus on switching variability, cycling enduranc,ememory stability.
You will co-integrate reliable designs on foundry-manufactured integrated circuits that are providedthe research consortium.
In collaboration with other team members you will conduct measurements demonstrating the ability of the memristive device for learning algorithms.
You have a master’s degree in physics, materials scienceelectrical engineering with an above-average academic performance.
You are interested in experimentalmultidisciplinary scientific work with a focus on technological content.
Furthermore, you are a team-oriented person that likes to work in interdisciplinary teamsyour are willing to engage in a lively scientific exchange.
You have a solid basic knowledge of semiconductor physicsintegration technology.
Not only are you fluent in German, but you also have a good command of the English language.
You are a very independenthighly self-motivated person, which is evident in your very reliableconscientious work style.
We work on the very latest issues that impact our societyare offering you the chance to actively help in shaping the change! We offer ideal conditions for you to complete your doctoral degree:
