We carry out a comparative study on resistive switching in Mn-doped ZnO thin films; samples grown Pt and Si show unipolar bipolar behaviors, respectively. Fittings of the current-voltage curves area dependence device resistance reveal filamentary conduction Pt/Mn:ZnO/Pt. On other hand, interfacial effect dominates Pt/Mn:ZnO/Si, its low state exponentially relaxes toward high contrast to good data retention Our results suggest that selecting electrodes dictates mechanism presumably by...
Summary In this paper, a new numerical method, element differential method (EDM), is proposed for solving general thermal‐mechanical problems. The key point of the direct differentiation shape functions Lagrange isoparametric elements used to characterize geometry and physical variables. A set analytical expressions computing first‐ second‐order partial derivatives with respect global coordinates are derived. Based on these expressions, collocation establishing system equations, in which...
A high-resolution grating interferometric micro-displacement sensor utilizing the subdivision interpolation technique is proposed and experimentally demonstrated. As interference laser intensity varies sinusoidally with displacement, a promising to achieve detection high resolution linearity. However, errors occur due phase imbalance, offset error, amplitude mismatch between orthogonal signals. To address these issues, circuit, along 90-degree phase-shifter high-precision DC bias-voltage...
Controlled synthesis of one-dimensional materials, such as nanowires and nanobelts, is vital importance for achieving the desired properties fabricating functional devices. We report a systematic investigation vapor transport growth SnO(2) nanostructures, aiming to achieve precise morphology control. are obtained when mixed with graphite used source material; adding TiO(2) into reliably leads formation nanobelts. Ti-induced modification crystal surface energy proposed be origin change. In...
We report on the correlated nonvolatile resistance and capacitance switching in Pt/LaAlO3/Nb:SrTiO3 heterostructures. The pristine devices show typical characteristics of a Schottky junction; however, after forming, reverse bias switches device into low high state while forward drives it state. Our experiments suggest that both formation conducting filaments modulation interface barrier contribute to switching. Oxygen vacancies play critical roles determining can be controlled process fabrication.
Thermal contact resistance (TCR) is a critical characteristic on increasing or decreasing thermal energy transmission efficiency between two bodies in management systems. However, it difficult to accurately determine the actual engineering structures, due complicated influence factors, such as pressure, temperature, and physical properties. In work, new method presented estimate for three-dimensional (3D) reusable heat-pipe cooled protection system based boundary measurements, by solving...
We fabricate regular arrays of nanoelectrodes on NiO thin films via nanosphere lithography and directly probe the nanoscale resistive switching using a conductive atomic force microscope. The unipolar is consistent with conducting filament formation/rupture mechanism, power as low 10−9 W. find that only about half devices are switchable, Monte Carlo simulation suggests strong correlations between reliability, electrode size, dimension density.
Different from gradient-based neural networks, a special kind of recurrent network has been proposed by Zhang et al for real-time matrix inversion. In this paper, we generalize such design method to solving online set linear time-varying equations. comparison with the resultant equation is designed based on vector-valued error function, instead scalar-valued function. It depicted in an implicit dynamics, explicit dynamics. Furthermore, globally exponentially converges exact solution...
We report that electrode engineering, particularly tailoring the metal work function, measurement configuration and geometric shape, has significant effects on bipolar resistive switching (RS) in lateral memory devices based self-doped SrTiO3 (STO) single crystals. Metals with different functions (Ti Pt) their combinations are used to control junction transport (either ohmic or Schottky-like). find electric bias is effective manipulating concentration of oxygen vacancies at metal/STO...
A new radial integration boundary element method (RIBEM) for solving transient heat conduction problems with sources and variable thermal conductivity is presented in this article. The Green's function the Laplace equation served as fundamental solution to derive boundary-domain integral equation. terms are first discretized before applying weighted residual technique that different from previous RIBEM a problem. Due strategy dealing terms, temperature, rather than approximated by basis...
