“…Therefore, the design of individual CNT is still needed to explore the effect of nanoscale lengths of CNTs on the rectenna effect of the visible range of EM radiation. The electrical characteristics including photodetection and memory characteristics of individual nanomaterials can be explored with the help of atomic force microscopy. − Our previous work investigated the rectenna effect of CNTs dispersed on different substrates like SiO 2 /Si and CuO/Cu . Similarly, the nanojunction material effect on the photoelectric response of single-wall carbon nanotube rectennas was also explored.…”

The optical rectenna is a device that converts the optical range of electromagnetic radiations to a direct current. Optical antennas, as for the radio frequency (RF) antennas, require an antenna's structure in the range of optical light EM wavelengths, i.e., a few hundred nanometers to a few micrometers. Herein, we demonstrate the optical rectenna effect of single-wall carbon nanotubes (SWCNTs) by cutting them in the resonance lengths of monopole nano-antennas (i.e., λ/4) of 100, 150, and 200 nm to convert incident red, green, and blue lights into a direct current. The physical engineering (cutting) of SWCNTs dispersed on SiO 2 /Si, comparable to one-quarter of the incident monochromatic light wavelength (i.e., red, green, and blue), is carried out with high-energy gallium (Ga) ion beams, with the help of a focused ion beam (FIB) system. The rectenna characteristics of these engineered SWCNTs are investigated using conductive mode atomic force microscopy (C-AFM). This unprecedented approach to investigating the optical rectennas will open more directions to study the rectenna effect at the nanometer scale.

“…22,40–43 Given the size of the NCs, between the molecular scale and microscopic devices, the concept of nano-Schottky is relevant, which takes into account a non-ideal SB due to the low dimensionality of the metal/semiconductor interface (ref. 27–29 and 35, see also a mini-review in ref. 44 and references therein).…”

“…[ 44 ] The resistive switching behavior highly depends on the device structure with an active layer based on the single material or heterojunctions of two different fabrics or composites of two materials. [ 45–50 ] The device structure engineering helps investigate the different working mechanisms like formation and rupture of conducting filament, redox reactions, ion (cations and anions) migration, and charge trapping and detrapping. [ 51–57 ] Researchers are improving memristor performance by investigating the active layer materials, device structure, and fabrication technology to operate on low power consumption, low operating voltage, and fast switching speed [ 58–61 ] for universal memory applications in the fields of signal processing, [ 62 ] logic circuits, [ 63 ] true number generator, [ 64 ] tunable filters, [ 65 ] and programmable analog circuits.…”

The aqueous electrolyte can be a deformable and stretchable liquid material for iontronic resistive memory devices. An aqueous medium makes a device closer to the brain‐like system with the movement of ions. This review paper proposes advances in liquid resistive memories and neuromorphic computing behavior to emulate electronic synapses. Primarily, the aqueous iontronic resistive memories can be used to study electrode and active layer materials and different device structures. Hence, herein, a timely and comprehensive study of these devices using ionic liquids, hydrogels, salt solutions, and soft electrodes to classify the device mechanism is presented. The filament formation is discussed in detail based on ion concentration polarization, electrode metallization, and movements of ions and charged molecules, which result in the formation of the metal dendrite. To manufacture a higher‐performance memory, device parameters should be optimized based on aqueous electrolytes, electrode materials, and other device design parameters. Aqueous electrolytes have smooth neurotransmission ability to fabricate brain‐inspired resistive memories with stable performance and device repeatability with smooth ion transmission. Aqueous electrode materials can be reliable for neural interface activities to compute electronic synapsis with electrical and chemical properties to ensure device reliability for a longer time period.
