Biography
So-Yeon Kim is a postdoctoral researcher in prof. Juan Bisquert’s PROFUND group at Instituto de Tecnología Química (ITQ) in Universitat Politècnica de València-Consejo Superior de Investigaciones Científicas (UPV-CSIC).So-Yeon Kim received her B.S. degree in Advanced Material Chemistry from Korea University in 2017 and Ph.D. degree in Chemical Engineering from Sungkyunkwan University under the supervision of Prof. Nam-Gyu Park in 2023. Her research topic has been focused on lowdimensional halide perovskites-based memristors in her Ph.D. course. She subsequently worked as postdoc researcher in Energy Frontier Research Institute in Sungkyunkwan University under the supervision of Prof. Nam-Gyu Park in 2023. Now, she started working as a postdoc researcher in Valencia, Spain from 2024. Her current research interests are expanded to halide perovskites-based memristive devices including memory and neuromorphic functions with various external stimuli, relating their complex ionic-electronic properties with harnessing hysteresis and dynamic time-dependent properties, etc. Their research work is supported by the European Research Council Advanced Grant (ErC- Perospiker).

[Abstract]
According to the advents of big data processing technologies and artificial intelligence (AI) generation, next-generation memristors have been in the spotlight as technologies to overcome the bottleneck limitations of von Neumann. Memristor (memory + resistor) is one of the key elements for high-performance integrated memory and neuromorphic computing applications with low energy consumptions and efficient processing. Among various memristor candidates, halide perovskites (HPs) have been actively studied as potential candidates for these devices due to their unique switching characteristics with low power consumption, simple fabrication, flexible integration compatibility across various sources for scalability, etc. However, there is still a lack of dynamic physical analysis and overviews about operating mechanisms and characteristics of HPs-based memristor and neuromorphic devices, which are essential for future application realization with high performance and accuracy. The seminar overviews the dynamic characteristics and operating principles of the HPs-based memristors and the basic neuromorphic devices. First, briefly introduce HPs-based memristors and neuromorphic applications and discuss different switching types/mechanisms according to the conducting pathway occurring inside the active HP layer. Also, show the analyze tools and physical dynamic models for the general insight to electrical actuation of the memory/neuromorphic systems from various perspectives.
