Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

Advanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...

GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching

Advanced Functional Materials, EarlyView.
The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Averaging Principle for Fractional Heat Equations Driven by Stochastic Measures [PDF]

Applied Mathematics Letters, 2020
In this paper, by utilising Besov space techniques, we establish the time averaging principle for a heat equation with fractional Laplace driven by a general stochastic measure $\mu$ which is assumed (only) to satisfy the $\sigma$-additivity in ...

Principles of Signal Analysis and Averaging

Neurologic Clinics, 1988
Averaging is the primary method for detecting small evoked potentials in the midst of surrounding electrical noise. Not all types of noise can be removed by averaging, however. The condition of the patient, electrodes, amplifiers, and filters are equally important for successful recording.

A nonlinear periodic averaging principle

Nonlinear Analysis: Theory, Methods & Applications, 2003
In a Hilbert space, a class of second-order evolution inclusions with an \(m\)-dissipative operator of special kind and a multivalued perturbation is considered. The perturbation is upper semicontinuous with compact convex values. Under assumptions on the perturbation expressed in terms of measure of noncompactness, an existence theorem and a nonlinear
