Abstract Direct observation of Cu in Cu-chabazite (CHA) zeolite has been achieved by electron ptychography using the Wigner distribution deconvolution. The imaging properties of ptychographically reconstructed images were evaluated by comparing the i

Abstract A physical reservoir device with tunable transient dynamics is strongly required to process time-series data with various timescales generated in the edge region. In this study, we proposed using the dielectric relaxation at an electrode–i

The temperature dependence of an intelligent connection (IConnect) device, in which an ionic liquid (IL) plays an essential role in a memristive function is presented in this study. An appropriate choice of IL and dissolved metal ion species can cont

Ionic liquids (ILs), non-volatile liquids composed of cations and anions, have various attractive properties for electronic devices, such as wide potential windows. Combining ILs with electronic devices is presumed to be able to provide new options f

We demonstrate a new memristive device (IL-Memristor), in which an ionic liquid (IL) serve as a material to control the volatility of the resistance. ILs are ultra-low vapor pressure liquids consisting of cations and anions at room temperature, and t

In a human brain, our closest and very low-power information processor, one neuron transmits electrical signals depending on the electrical stimulation from other neurons. Therefore, it can be regarded as the multi-input one-output system that is the

Functional oxides with strongly correlated electron systems, such as vanadium dioxide, manganite, and so on, show a metal-insulator transition and an insulator-metal transition (MIT and IMT) with a change in conductivity of several orders of magnitud

RF magnetron sputtered titanium oxide (TiO2-x) thin films were used as active channel layer to fabricate field-effect transistors (FETs). In the as-prepared FETs, poor FET performance was found, with a low on-to-off current ratio of ∼500 and a high

Herein, a physical reservoir device that uses faradaic currents generated by redox reactions of metal ions in ionic liquids was developed. Synthetic time-series data consisting of randomly arranged binary number sequences ("1" and "0") were applied a
