Investigating the Role of Interfacial Layer for Resistive Switching in a Hybrid Dion-Jacobson Perovskite-Based Memristor

Interface Engineering Enables Multilevel Resistive Switching in Ultra-Low-Power Chemobrionic Copper Silicate

“…These synapses play a pivotal role in facilitating the communication between neurons. Specifically, synapses involve a presynaptic neuron responsible for signal initiation or transmission and a postsynaptic neuron that receives the transmitted signals. , In our investigation involving memristors constructed with copper silicate chemical garden-based materials, the constituent elements of the device architecture draw parallel to the biological components of neural communication. Specifically, the top electrode and bottom electrode of the memristor analogously represent the presynaptic neuron and the postsynaptic neuron, respectively (Figure a).…”

“…The human brain is an exceptionally high-density neural network with 10 12 neurons and 10 15 synapses. The goal of neuromorphic electronics is to physically mimic human brains. − In particular, artificial synapses have been developed to mimic biological synaptic processes because synapses play a vital role in learning and memory in the brain. , Due to their advantages of high-density integration in a cross-bar array, multilevel memory, and good scalability, memristors as 2-terminal devices have been regarded as essential parts of neuromorphic computation. − Organic materials and hybrid organic–inorganic perovskites (HOIPs) have recently been used in their construction, although they have traditionally been made mostly of inorganic materials. − Because of their mechanical flexibility and biocompatibility, organic memristors have a wider range of applications, including wearable and implantable computing devices. − However, the presence of lead in hybrid perovskites is a major bottleneck of commercialization.…”

From fundamentals to frontiers: a review of memristor mechanisms, modeling and emerging applications

“…In ReRAM, hybrid perovskite materials are used as the switching medium to control the resistance state of the device. 153,[157][158][159][160] The resistance state is determined by the formation and rupture of conductive filaments within the hybrid perovskite material. Hybrid perovskite ReRAM devices have demonstrated high on/off ratios, low power consumption, and fast switching speeds, making them a promising candidate for future memory applications.…”

Slow Migration-Controlled Resistive Switching in Stable Dion–Jacobson Hybrid Perovskites for Flexible Memristive Applications

“…Unlike their three-dimensional counterparts, these low-dimensional phases incorporate hydrogen bonds between the organic and inorganic layers . This structural modification renders them considerably more stable in ambient air, as the hydrophobic nature of the organic layers effectively repels moisture penetration. − Furthermore, hydrogen bonds also reinforce the mechanical stability for flexible applications by providing additional intermolecular forces that support the crystal lattice. In this work, a flexible memristor device is presented by a complete solution process, featuring an active layer of Dion–Jacobson hybrid organic–inorganic perovskites (HOIPs) with an ON/OFF ratio of 10 2 , long data retention measured up to 35 h, and data endurance measured up to 1000 cycles.…”
