Lead-free halide perovskite memristors modified with buffer layers for sustainable and high-performance neuromorphic computing

Project description

Sustainable and high-performance neuromorphic computing with lead-free perovskite memristors

The rapid digital transformation has led to vast amounts of data, creating the necessity for more energy-efficient computing technologies. Neuromorphic computing, inspired by the brain’s structure and function, aims to enable energy-efficient parallel information processing. Memristors based on halide perovskites are promising for this application. However, the most efficient perovskite devices typically contain toxic lead-based halide perovskites (Pb-HPs), posing important challenges for practical applications. With the support of the Marie Skłodowska-Curie Actions programme, the MemSusPer project will develop innovative, sustainable Pb-free HP memristor devices with high stability, performance, reproducibility and low energy consumption. To achieve this, the project will conduct key research along with a leading expert in the field to overcome current challenges and demonstrate the technology.

Objective

The World's digital transformation generates vast amounts of data daily. Conventional computing technologies face serious challenges in efficiently handling all this information, leading to high energy consumption. Neuromorphic computing offers a more efficient solution by designing systems inspired by the structure and function of the human brain, which processes information in parallel with minimal energy consumption. A key component in this technology is the memristor, a novel electronic element that mimics the synapses and spiking processes of neurons. The memristors containing lead-based halide perovskites (Pb-HPs) are among the best-performing, but the presence of toxic Pb hinders their practical application.
MemSusPer aims to develop sustainable, Pb-free HP memristor devices with high performance, stability, reproducibility, and low energy consumption. This will be achieved through two main strategies: (1) enhancing the quality of the perovskite films, and (2) using novel buffer layer materials, such as organic mixed ionic electronic conductors, to regulate the ions migration and induce new energy-efficient activation/deactivation mechanisms. I will conduct the research at the Institute of Advanced Materials (University Jaume I, Spain) with the guidance of Prof. Antonio Guerrero, a leading expert in the field. To validate the developed technology, a 4x4 memristor array will be fabricated using the advanced infrastructure of the Institute of Emerging Technologies (Hellenic Mediterranean University, Greece). MemSusPer is committed to advancing next-generation neuromorphic computing, which is not only high-performing but also eco-friendly, contributing to the green and digital transitions prioritised in the European Union's agenda. The multidisciplinarity and high impact of MemSusPer, combined with the training component of the MSCA-PF, will help me become a tenured independent researcher, expand my expertise, and strengthen my academic profile and networks.
