“…Reduction and nucleation lead to the formation of filament toward the TE resulting in resistive switching. Similar observations regarding the formation of oxygen‐vacancy‐rich conduction path have been reported in bio‐organic devices based on gelatin and chicken egg albumen . Nevertheless, resistive switching in the device with Au TE are due to the formation of neither metallic nor oxygen vacancy filaments, as indicated by its TOF‐SIMS depth profiles (Figure k).…”

To enable long-term progress, next-generation nonvolatile memories should function on the basis of new concepts that are different from the conventional charge storage in floating-gate transistors. [4][5][6] Of the emerging storage principles, electrically modulated resistive switching behaviors in metal-insulator-metal (MIM) structures could be an intriguing concept to redefine the frontiers of next-generation nonvolatile memories. [7][8][9][10][11][12][13][14] Such implementation offers promising advantages in several key aspects, including down-scalability, switching speed, power consumption, and fabrication cost.Resistive switching has been demonstrated in a wide variety of inorganic [7][8][9][10] and organic [11][12][13][14] materials, which are generally deposited as a continuous thin film sandwiched in between two conductive electrodes forming a MIM structure. However, careful consideration should be taken during the fabrication process, because deposition of these materials using various power-demanding methods (e.g., thermal evaporation, molecular beam epitaxy, and chemical vapor deposition) could possibly lead to an energy-imbalance situation. [15] Furthermore, utilization of materials derived from nonrenewable resources (e.g., mined minerals and fossil fuels) could raise critical issue regarding sustainability. In general, these materials are chemically robust and thus require an infinitely long period for natural decomposition after disposal, leaving behind massive volumes of electronic waste overwhelming landfills around the world. [16] In tandem with the growing environmental awareness and the proliferation of disposable electronics, there is an urgent need to develop more electronic applications based on the greener bio-organic materials, [16,17] which are generally derived from living (or once-living) organisms that are abundant in the nature. Bio-organic materials are not only biodegradable, biocompatible, and environmentally benign to provide a sustainable solution in addressing the environmental concerns, but also exotic for next-generation electronics realization. Recently, resistive switching behaviors demonstrated in several bio-organic MIM structures (Table S1, Supporting Information) have garnered considerable attention owing to their potentials as a plausible alternative for next-generation nonvolatile memories.Growing environmental awareness has prompted a paradigm shift toward using green materials for various electronic applications. Bio-organic materials are promising candidates attributable to their inherent biocompatibility, biodegradability, and environmental friendliness. Here, a nonvolatile memory device based on resistive switching in a bio-organic polysaccharides film is presented. The polysaccharides are extracted from natural Aloe vera gel using facile alcohol precipitation. Optimal film deposition is achieved through spin-coating followed by drying at 120 °C, which is higher than the usual processing temperature of commercial Aloe vera gel. Both bipolar and unipolar resistiv...

The von Neumann bottleneck constrains developments of conventional artificial intelligences (AIs) toward portable, energy efficient, and truly brain‐like systems. Biological synapses connecting neurons deliver neural action potentials by regulating neurotransmitters between presynaptic and postsynaptic membranes. In a similar way, ionotronic transistors and memristors transmit electronic signals through the migration of ionic species in dielectric and resistive switching electrolyte under external electrical field. Thus, utilizing ionotronic devices to emulate synapses and building bionic neural networks opens up a brand‐new path to realize hardware‐based AI. Moreover, it would allow the fabrication of an artificial perception learning system to mimic the human perception system with multi‐sensory learning abilities. This review presents ionotronic devices for neuromorphic engineering applications. The operation mechanisms and brain‐inspired synaptic responses and neural functions are discussed. At last, outlooks for ionotronic devices to construct bionic neural networks are provided.

human life. [1][2][3] To achieve such a dream, choosing natural biomaterials such as nucleic acids, [4][5][6] peptides, [7] proteins, [8,9] and polysaccharides [10] as the substitutes of fossil source-based synthetic chemicals is a promising way. Correspondingly, micro/ nanoscale fabrication on natural biomaterials receives great of importance, [11] and a spatially definable property with high precision to exactly position biomaterials on a surface is highly desirable [12][13][14][15][16][17][18] toward biodegradable and biocompatible green electronic, [19][20][21][22] optical, [23][24][25][26][27][28][29] sensor, [30] energy, [31] and environmental devices. [32] Typical examples down this road include silk fibroin, [12][13][14] polysaccharides, [10] and DNA origami-mediated lithography. [5] These approaches are part of great efforts to develop "green" lithographic processing in semiconductor industry that is eligible to lessen the exposure of workers and environment toward noxious chemical and reduce waste. [13] The adoption of these strategies allows the replacement of organic solvent with water to cast and develop a resist, accompanied with the exclusion of environmentally harmful components from material processing and fabrication. However, so far the lithographic processes based on existing natural biomaterials are difficult to be exploited in scale-up industrial application, because their limited quantities, high material, and processing cost as well as small deposition area impede the practical engineering of these biomaterials. [9] Moreover, the less-controlled variation on polymorph and polydispersity of biomaterials often influences the repeatability of results. [33] Recently, our group reported the use of phase-transited lysozyme nanofilm as the resist for photolithography and electron-beam lithography (EBL), with the cost being decreased and practical applicability being potentially demonstrated. [17] Continuous efforts along this way further require much cheaper material and simpler fabrication process for large-scale industrial uses. In this respect, we pay attention to egg white due to the following reasons. First, egg white is a very common natural biomaterial just taken from egg as our daily food, which makes it has great natural abundance with a low cost. Second, in contrast to other natural competitors usually requiring strict demands on the purity, polydispersity, and polymorph stability, egg white is a combination of multiple functional nutrients, [34] which could be directly utilized without further purification and Complex lithographic steps and the use of toxic chemicals in these processes are in conflict with a sustainable human society. Development of new inexpensive and green resist, simple alternative procedures, and nontoxic solvents is the key to move recyclable micro/nanofabrication from laboratory level to industrial application in large scale. Herein, precise control on protein fragmentation/aggregation upon photo/electron irradiation is conceived into egg white-based green resist...
