Photovoltaic memristors based on photoelectric synaptic plasticity of a bulk photovoltaic effect device

Abstract

Memristor, with synaptic plasticity similar to biological synapses, is recognized as one of the key devices to reach computing in memory and overcome the Von Neumann bottleneck. Herein, we develop...

Photoelectric Memristor-Based Machine Vision for Artificial Intelligence Applications

“…Considering the above issues, the existing limitations of photoelectric memristors are analyzed, and the key to the development of these technologies lies in the selection of materials and the design of device structures. , At the material level, it can be seen that two-dimensional (2D) materials, perovskite materials, inorganic materials, organic materials, biomaterials, etc. can be used to prepare high-performance memristors. − However, some technical problems and inherent defects of the materials still affect the further development of photoelectric memristors to some extent. For example, for 2D materials, although it has been reported that 2D materials can be grown at the wafer scale, the problem of large-scale and high-quality growth of 2D materials is still a problem to be solved due to the immaturity of growth technology and the low material transfer efficiency.…”

Contrasting analog and digital resistive switching memory characteristics in solution-processed copper(i) thiocyanate and its polymer electrolyte-based memristive devices

“…12,13 Similarly, the self-powered memristive device is a new trend where hybrid device architectures are designed with nanogenerators, thin film solar cells, etc. [14][15][16][17] Memristive devices endowed with such varied functionalities and multiple memory characteristics owe much to the switching medium. This work focuses on copper thiocyanate (CuSCN) as a promising switching medium.…”

Acquiring Bulk Photovoltaic Effect in One-Dimensional Sn-Based Perovskite Single Crystals by Nonlinear Organic Diamine

“…The power conversion efficiency of photovoltaic devices is usually lower than the Shockley-Queisser (SQ) limit . In noncentrosymmetric materials, photogenerated carriers can be separated spontaneously due to the existence of internal polarized electric fields, which is called the bulk photovoltaic effect (BPVE). − BPVE materials as interlayer are expected to improve efficiency of photovoltaic devices if the polarized electric field can be controlled to strengthen the build-in potential. , It also has broad application prospects in self-powered photodetection, − memristor, solar cells, and spintronic devices; BPVE especially exists in semiconductor material. In recent years, the research on BPVE has gradually expanded from inorganic ferroelectrics to van der Waals, , organic, and OIHP materials .…”
