A New Threshold Switching Device With Tunable Negative Differential Resistance Based on ErMnO3 Polymorphs

open access: yesAdvanced Functional Materials, EarlyView.
Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Newton's method for stochastic functional differential equations

open access: yesElectronic Journal of Differential Equations, 2012
In this article, we apply Newton's method to stochastic functional differential equations. The first part concerns a first-order convergence. We formulate a Gronwall-type inequality which plays an important role in the proof of the convergence theorem

Action Functionals for Stochastic Differential Equations with Lévy Noise

open access: yesCommunications on Stochastic Analysis, 2019
By using large deviation theory that deals with the decay of probabilities of rare events on an exponential scale, we study the longtime behaviors and establish action functionals for scaled Brownian motion and Lévy processes with existing finite exponential moments.
