Tunability of near infrared opto-synaptic properties of thin MoO3 films fabricated by atomic layer deposition

Nanoscale Ni/Mo/MoO3/Ni memristor for synaptic applications

“…Thin MoO 3 films have a high work function (∼5.5 eV), enabling efficient ion migration with thermal stability and a wide band gap (∼3.0–3.8 eV), providing good electrical insulation and stable RS behaviour [17]. In addition, atomic layer deposition (ALD) fabrication of thin MoO 3 films requires only 250°C [18]. To ensure effective charge carrier movement between electrodes and the active layer, the Nickel (Ni) metal electrode with a relatively low work function (∼5 eV) and high conductivity is chosen [17].…”

Centimetre-scale single crystal α-MoO3: oxygen assisted self-standing growth and low-energy consumption synaptic devices

“…It has provided inspiration for the preparation of wafer-scale ultra-thin MoO 3 films. 25 Li et al grew a large-scale 2D single crystal α-MoO 3 through controlling the quartz tube diameter; 21 the controllable synthesis of large-scale single crystal α-MoO 3 still faces challenges owing to the insufficient understanding of the α-MoO 3 nanosheet growth mechanism.…”

One‐Phototransistor–One‐Memristor Array with High‐Linearity Light‐Tunable Weight for Optic Neuromorphic Computing

“…These factors are a significant challenge in conventional CMOS systems mainly because of the physical separation of the functional components, including sensory, computing, and memory units. [ 1–6 ] Driven by the human vision architecture, optic neuromorphic devices like photonic memristors, [ 7–18 ] have been developed for use as neuromorphic vision sensors, and they have shown great promise in combining optic sensing, memory, and processing functions in the same device. [ 4,17,19–21 ] Therefore, preprocessing and computing of the images in vision sensors can be efficiently realized at the edge rather than in cloud sever systems.…”
