Advertising division: PGI-7 - Electronic Materials
Reference number: 2019D-233


The Peter Grünberg Institute (PGI) is the central platform for basic research in the field of nanoelectronics and combines cutting-edge research, technology development and innovative device concepts. Our strong basic research in solid state physics and materials science paves ground for the discovery and use of novel electronic phenomena, methods, and materials. At Electronic Materials Department (PGI-7), our research focuses on the fabrication of oxide thin films and nanoelectronic devices for novel computing paradigms such as neuromorphic computing.

The PGI-7 is involved in a Marie-Curie training network “Materials for Neuromorphic Circuits” (MANIC) that is aiming to synthesize materials that can function as networks of neurons and synapses by integrating conductivity, plasticity and self-organization. Within MANIC, the PGI-7 offers a PhD project that aims to engineer the synaptic plasticity of epitaxial and polycrystalline memristive oxide thin film devices from short-term plasticity to long-term potentiation. This so called metaplasticity inherent to biological systems will be employed to implement different types of learning algorithms. The plasticity will be modified by the interplay of thin film processing conditions (defects, interfaces) and the sequence of electrical stimuli. The project should clarify the interplay between pristine microstructure, filament formation, dynamics of oxygen vacancy movement and synaptic plasticity. The memristive devices will finally be co-integrated into a neuromorphic CMOS chip designed at Bielefeld University.

We are offering a
