Time-Domain Analysis of Chalcogenide Threshold Switching: From ns to ps Scale
نویسندگان
چکیده
A space- and time-dependent theoretical model based on a trap-assisted, charge-transport framework for the amorphous phase of chalcogenide material is used here to interpret available experimental results electric current nanoscale devices in ns–ps time domain. numerical solution constitutive equations bias has been carried out GST-225 devices. The “intrinsic” rise device after application suitable external controlled by microscopic relaxation mobile-carrier population steady-state value. Furthermore, analysis extended include effect circuit electrical switching. quantitative estimate delay due unavoidable parasitic effects made optimised set up configurations recently groups.

Large Scale Experiments Data Analysis for Estimation of Hydrodynamic Force Coefficients Part 1: Time Domain Analysis
This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...
متن کاملPiezoresponse force microscopy studies of switching behavior of ferroelectric capacitors on a 100-ns time scale.
Piezoresponse force microscopy is a powerful technique for nm-scale studies but is usually limited by response time. In this Letter, we report the first direct studies of ferroelectric capacitor switching on a submicrosecond time scale. Simultaneous domain imaging and sub-mus transient current measurements establish a direct relationship between polarization P(t) and domain kinetics. Switching ...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولCorrections to ns and nt from high scale physics
When modeling inflaton fluctuations as a free quantum scalar field, the initial vacuum is conventionally imposed at the infinite past. This is called the Bunch-Davies (BD) vacuum. If however an asymptotically Minkowskian past does not exist, this requires modifications. We derive corrections to the scalar spectral index ns and the tensor tilt nt descending from arbitrary mixed states or from ex...
