Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.

Anisotropy Induced by Electric Charge: A Computational Analytical Approach

open access: yesPhysics
This paper presents a novel class of interior solutions for anisotropic stars under the imposition of a self-similar symmetry. This means proposing exact solutions to the Einstein field equations to describe charged matter distribution with radiation ...

On linear equations of anisotropic elastic plates [PDF]

open access: yesQuarterly of Applied Mathematics, 1965
Abstract : A generalized Hamilton's principle and the associated variational equation of motion for linear and anisotropic elastic plates are deduced from their counterpart in general elasticity theory through expansion of the displacement and strain in infinite power series in the manner of Cauchy and Mindlin, and by carrying out the integration in ...

Pentagonal 2D Altermagnets: Material Screening and Altermagnetic Tunneling Junction Device Application

open access: yesAdvanced Functional Materials, EarlyView.
From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Investigation of the Effects of Strain and Electric Field on the Spin‐State Energetics of Co‐Doped BaTiO3 and PbTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Ab initio calculations using the r2SCAN functional show that biaxial strain does not alter the high spin preference of cobalt‐doped BaTiO3 and PbTiO3; a small compressive uniaxial strain however results in an equally favorable low spin state for BaTiO3 and thus bistable magnetism.

The Role of Symmetry and Separation in Surface Evolution and Curve Shortening

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
With few exceptions, known explicit solutions of the curve shortening flow (CSE) of a plane curve, can be constructed by classical Lie point symmetry reductions or by functional separation of variables.
