Two Postdoctoral Researchers in Memristor Materials and Devices, University of Turku, Finland

Summary

The Department of Physics and Astronomy at the University of Turku invites applications for two fixed-term Postdoctoral Researcher positions within the Memristor and Neuromorphic Computing Research Group (Wihuri Physical Laboratory). The positions address complementary challenges in next-generation memristive and neuromorphic technologies:

• Track A: Scalable memristor crossbar-device fabrication, yield, and reliability (OCEANAut / Business Finland project).
• Track B: Perovskite quantum dots and semiconductor nanomaterials for artificial synapses (Research Council of Finland project).

Applicants may apply for either Track A, Track B, or both (indicating track preference in the motivation letter).
