Exploring self-organized material platforms for brain-like computing
Together with our colleagues from the CRC 1461 "Neurotronics" we strive to explore the primitives of neural-like assemblies with the aim to establish a broad material platform for brain-like computing. Using tailored AgAu alloy nanoparticles as nanoscopic building units, nanoparticle networks poised at the percolation threshold can be fabricated, which are showing promising brain-like resistance change features.

Where are our nanoparticles?
The researcher Jonas Drewes applies a variety of photon-based in-situ diagnostic methods to uncover the spatial and temporal characteristics of nanoparticle growth in a gas aggregation source.
Recenty, in a work by Jonas Drewes et al., the dynamic trapping processes inside a gas aggregation cluster source were made visible by laser light scattering.Click here to find the full publication in Particle & Particle Systems Characterization.
How do nanoparticles relate to synapses and large scale neural networks?
The researchers Blessing Adejube, Rohit Gupta, Alexander Vahl and Niko Carstens (left to right) investigate, how metal, metal alloy and metal oxide semiconductor nanoparticles can be used to create electrical devices that mimic aspects of information processing in neurons and synapses.
Recenty, in a work by Niko Carstens et al. the group found brain-like critical dynamics and long-range temporal correlations in percolating networks of silver nanoparticles. Interestingly, this functionality is preserved after integration of the nanoparticles into an insulating matrix. Click here to find the full publication in Nanoscale Advances.
