New device concepts and new computing principles are needed to balance our ever-growing appetite for data and information with the realization of the goals of increased energy efficiency, reduction in CO 2 emissions and the circular economy. Neuromorphic or synaptic electronics is an emerging field of research aiming to overcome the current computer's Von-Neumann bottleneck by building artificial neuronal systems to mimic the extremely energy efficient biological synapses. The introduction of photovoltaic and/or photonic aspects into these neuromorphic architectures will produce self-powered adaptive electronics but may also open up new possibilities in artificial neuroscience, artificial neural communications, sensing and machine learning which would enable, in turn, a new era for computational systems owing to the possibility of attaining high bandwidths with much reduced power consumption. This perspective is focused on recent progress in the implementation of functional oxide thinfilms into photovoltaic and neuromorphic applications towards the envisioned goal of selfpowered photovoltaic neuromorphic systems or a solar brain.

“…The problem with this idea is that the LSPR generally presents a transient photoresponse; however, an optoelectronic memristor usually requires not only the photoresponse capability but also a persistent conductance change ΔG induced by light irradiation. [ 34,35 ] Importantly, Ohko et al. proposed a photochromic nanocomposite composed of a TiO 2 film loaded with Ag nanoparticles (NPs) that can change its color reversibly with persistent properties under both ultraviolet (UV) light and visible (vis) light.…”

Plasmonic Optoelectronic Memristor Enabling Fully Light‐Modulated Synaptic Plasticity for Neuromorphic Vision

et al. 2021

Exploration of optoelectronic memristors with the capability to combine sensing and processing functions is required to promote development of efficient neuromorphic vision. In this work, the authors develop a plasmonic optoelectronic memristor that relies on the effects of localized surface plasmon resonance (LSPR) and optical excitation in an Ag–TiO2 nanocomposite film. Fully light‐induced synaptic plasticity (e.g., potentiation and depression) under visible and ultraviolet light stimulations is demonstrated, which enables the functional combination of visual sensing and low‐level image pre‐processing (including contrast enhancement and noise reduction) in a single device. Furthermore, the light‐gated and electrically‐driven synaptic plasticity can be performed in the same device, in which the spike‐timing‐dependent plasticity (STDP) learning functions can be reversibly modulated by visible and ultraviolet light illuminations. Thereby, the high‐level image processing function, i.e., image recognition, can also be performed in this memristor, whose recognition rate and accuracy are obviously enhanced as a result of image pre‐processing and light‐gated STDP enhancement. Experimental analysis shows that the memristive switching mechanism under optical stimulation can be attributed to the oxidation/reduction of Ag nanoparticles due to the effects of LSPR and optical excitation. The authors' work proposes a new type of plasmonic optoelectronic memristor with fully light‐modulated capability that may promote the future development of efficient neuromorphic vision.

“…In previous reports, memristive devices have shown potential wide applications in the analog circuit domain such as audio electronics, radio communications, noise cancellation circuits, etc. − The as-fabricated device capable of switching between a capacitive device at LVD and resistive device at HVD would enable some novel applications. In particular, these different devices exhibit an acceptable performance fluctuation (Figure S11, Supporting Information).…”

It is well-known that the reprogrammable device is one of the important needs for circuit design. In this paper, nanolayered TiO2 and maple leaves (ML) are combined to form a functional layer (TiO2-ML) inside memristive devices, which demonstrate both the capacitive effect and the nonvolatile storage capability. When the voltage increases from zero, the device first enters a capacitive-coupled memristive state at low voltage before switching to a normal memristive state at a higher voltage. The existence of the capacitive behavior results in a nonzero-crossing I–V characteristic different from the zero-crossing curve observed in normal memristive device. Utilizing this capacitive-coupled memristive behavior, we design a low power passive filter with applications toward reprogrammable analog circuit designs, paving a path toward a multifunctional nanodevice in the future.
