Memristive Devices for Neuromorphic Systems

Within this research area, thin-film technology is employed for the fabrication of memristive devices (material deposition, lithography, etching). The fabricated devices must meet the special requirements of bio-inspired computational architectures, so-called neuromorphic systems, that they therewith enable the realization of novel electronics. This particularly requires the development of suitable device technologies for a wafer scale fabrication of memristive devices.
