Memristor is an ideal electronic device used as artificial nerve synapse due to its unique memory function. This article presents a design of new Hopfield neural network (HNN) that can generate multiscroll attractors by utilizing memristor in the HNN. Differing from others, this constructed with hyperbolic tangent functions. Taking self-feedback neuron HNN, memristive HNN yield multidouble-scroll attractors, and parameters be effectively control number double scrolls contained attractor....
We report, for the first time, design and fabrication of a nanoparticle-based nanomotor system by directly self-assembling nanoparticles onto functional, nanometer-thin lamellae, such as polymer single crystals. Tens thousands judiciously selected (gold, iron oxide, platinum nanoparticles) with sizes ranging from <5 to few tens nanometers have been introduced into via directed self-assembly. The resulting realizes functions autonomous movement, remote control, cargo transportation utilizing...

In this letter, gate leakage mechanisms in different contact normally off p-GaN/AlGaN/GaN high electron mobility transistors (HEMTs) have been studied by the temperature-dependent current-voltage (IG-VG) measurement. It is found that two-dimensional variable range hopping responsible for current at reverse bias and low forward both high-leakage low-leakage Schottky devices. At bias, case of contact, dominant conduction mechanism to be thermionic field emission while it Poole–Frenkle (PFE)...
Abstract The AlO x -based resistive switching memory device is fabricated by an oxidation diffusion process that involves depositing Al film on ITO substrate and annealing at 400 °C in a vacuum. An interface layer with thickness of ~ 20 nm formed as resistance layer. Bipolar unipolar (RS) behaviours are obtained when the compliance current limited (≥ 1 mA). In RS behaviour, devices fail to perform set/reset cycles low temperature (40 K), which suggests Joule heating essential for behaviour....
