Abstract:
Memristors have garnered significant attention from the scientific community due to their potential to revolutionize computing paradigms. These devices possess the unique ability to alter their conductive state based on the history of voltage stimuli they receive. In this presentation, I will introduce the fundamental characteristics of memristors and explore the various types available. Subsequently, I will discuss critical parameters that influence the ability of memristors to change states and retain memory. We will learn how to identify these parameters in current-voltage (I-V) characteristics and differentiate between types of memristors.
The focus will then shift to the characterization of memristors using various I-V techniques, such as I-V sweeps, voltage pulses (both single and trains), and impedance spectroscopy. We will specifically examine the characterization of halide perovskite memristors and multipore nanofluidic memristors. I will briefly explain the insights we can derive from these techniques, how to correlate them, and how to extract parameters crucial for applying memristors in neuromorphic systems, such as the relaxation time.
Currículum:
Agustín Bou graduated in Physics from the University of Valencia in 2016. He then joined Prof. Juan Bisquert’s team at Universitat Jaume I, where he earned a Master’s degree in Applied Physics in 2017 and received an FPI scholarship to pursue his PhD. His thesis research focused on the modeling and characterization of perovskite solar cells using small perturbation techniques. During his PhD, he visited University of Granada, where he modeled the heterojunctions of perovskite solar cells, and Swansea University, where he investigated perovskite devices using light-modulated techniques (IMPS and IMVS). Later in his PhD, he concentrated his research on perovskite memristors, where he applied his expertise in impedance spectroscopy gained when studying solar cells. He obtained his PhD in 2023 after publishing 12 articles. He continued his research for an additional 6 months in Prof. Bisquert’s group, investigating memristors made of halide perovskites and nanopores. Currently, he is a Postdoctoral Researcher at the Leibniz Institute for Solid State and Materials Research (IFW Dresden) as part of Prof. Yana Vaynzof’s group, where he continues his research in perovskite memristors.
