Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Convergence Analysis of an Alternating Nonlinear GMRES on Linear Systems

Numerical Linear Algebra with Applications
ABSTRACT In this work, we develop an alternating nonlinear Generalized Minimum Residual (NGMRES) algorithm with depth and periodicity , denoted by aNGMRES(), applied to linear systems. We provide a theoretical analysis to quantify by how much one‐step NGMRES() using Richardson iterations as initial guesses can improve the convergence
