The IrO2 top electrode chemistry of ferroelectric IrO2/Hf0.5Zr0.5O2 (HZO)/IrO2 metal–insulator–metal (MIM) structures dependent on rapid thermal annealing in different gas atmospheres (nitrogen, oxygen, and forming [FG]) is investigated. Using hard X-ray photoelectron spectroscopy (HAXPES), the strongly modified chemical states layer choice atmosphere are observed. For O2 N2 anneals, remains ei...

Short- and long-term neuroplasticity behaviors are key mechanisms for various activities. In this paper, we propose a synaptic transistor with floating-gate (FG) node an amorphous InGaZnO (IGZO) channel layer. The proposed device emulates the functions of both short-term memory (STM) (LTM) through control amplitude number input pulses. STM operated by ion movement in gate dielectrics occurs whe...

A study of the long-range, local and electronic structure of Nd0.5Sr0.5MnO3 films of varying thickness between 500 and 2000 Å has been performed. Local structure measurements at the Sr K-edge reveal a reduction of the Mn–O–Mn bond angles in films below 1000 Å. Spin-polarized measurements reveal splitting of the Mn 3d eg state in the strained region of the films and are consistent with a two-lay...

The functionalized graphene/montmorillonite (FG/MTT) nanosheet was synthesized through chemical bonding by a simple, green method, which had remarkable dispersion stability in oil and its lubricating performance evaluated four-ball tribometer. test results showed that FG/MTT preeminent lubricant property when the concentration 0.4 mg/ml. Compared with bare sample, average friction coefficient (...

Abstract A study of smart functionally graded (FG) beams made carbon nanotube (CNT) reinforced composites combined with piezoelectric materials is presented. The material parameters the composite are assumed to vary along their thickness following extended rule mixture. finite element (FE) model was developed for FG nanotube-reinforced beam materials. This tested against previously published st...

In the eastern Alboran Sea, frontogenesis (FG) is a dominant process for fronts extending from Spanish coast toward basin interior, promoting large vertical displacements that connect surface mixed layer with oceanic interior. Using realistic, high-resolution model simulation this region, we conduct offline advection of virtual water parcels released near during 2-day episode intense FG. Three-...

Redox capacitor, which is one type of supercapacitor, has been attracted tremendously as it shows a satisfactory specific capacitance, good cycle ability, and stability. The present study reveals redox capacitor fabricated with an ionic liquid (IL)-based gel polymer electrolyte (GPE). Electrodes the were conducting polymer, polypyrrole (PPy). composition GPE was polyvinylidenefluoride–co-hexafl...

this article deals with the buckling analysis of perfectly bonded cross-ply laminated composite plates reinforced by wavy carbon nanotubes (cnts) under in-plane loads using element free galerkin (efg) method based on first-order shear deformation theory (fsdt). the wavy single-walled cnts and poly-co-vinylene are used for the fibers and the matrix, respectively. the cnt fibers are distributed i...
