Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films
Advanced Functional Materials, EarlyView.We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Advanced Functional Materials, EarlyView.A 6‐in wafer‐scale atomic‐layer‐controlled tungsten disulfide (WS2) is achieved by combining plasma‐assisted synthesis with three‐gas reactive ion etching. Precise layer control enables tunable band‐gap evolution and pulse‐history‐dependent opto‐memristive dynamics.

A Priori Estimates or Elliptic Systems
Zeitschrift für Analysis und ihre Anwendungen, 1987 A priori estimates for the general complex Beltrami equation in connection with Riemann–Hilbert boundary conditions are developed, which can be used for existence as well as uniqueness statements for related nonlinear problems. For this reason the equation together with the boundary conditions are transformed into the canonical form and essentially a ...

An Overlooked Transport Mechanism in Organic Mixed Conductors
Advanced Functional Materials, EarlyView.Electrical transport in organic mixed ionic‐electronic conductors is commonly described by ionic and electronic conduction. Here, eumelanin reveals that polarization‐assisted displacement currents constitute an additional transport component that coexists with conductive transport.

A note on nonlinear elliptic systems involving measures
Electronic Journal of Differential Equations, 2000 We study the existence and regularity of solutions to nonlinear elliptic systems whose right-hand side is a measure-valued function. Using a sign condition instead of structure conditions, we obtain the same as those presented by Dolzmann, Hungerbuhler ...

Optimal boundary control for a time dependent thermistor problem
Electronic Journal of Differential Equations, 2009 An optimal control of a two dimensional time dependent thermistor problem is considered. The problem consists of two nonlinear partial differential equations coupled with appropriate boundary conditions which model the coupling of the thermistor to ...
