Memristive devices are currently explored for neuromorphic and emerging unconventional computing concepts towards future low-power computing systems. These devices have been proposed as: (i) computing elements to support in memory computing in neural networks, (ii) building blocks to reproduce in hardware synaptic or neural functionalities, and (iii) key elements to build nonlinear dynamical circuits. In this framework, both volatile and non-volatile resistance switching memristive devices are widely studied to engineer various computing functions [1].
This talk will present our recent results in the field of volatile electrochemical memristors based on the Ag/SiOx/Pt structure and how to implement neuromorphic functionalities such as short-term plasticity, paired-pulse facilitation and inhibition, and integrative functions. We will discuss how the interplay between switching times and relaxation effect controls the memristors dynamics and possible various switching modes that can be used to reproduce key synaptic and neuronal functions [2].
The second part of the talk will discuss an unconventional computing approach based on analogue Pt/HfO2/TiN RRAM devices. We exploit the programmable nonlinearity of the non-volatile memristors to build an analogue nonlinear dynamical circuit based on the Murali- Lakshmanan-Chua (MLC) architecture [3]. The circuit can be tuned from periodic to chaotic behavior through the modulation of an input signal. We demonstrate its processing ability in an approach based on single-node reservoir for various nonlinear classification tasks.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
