Tunnel magnetoresistance in asymmetric double-barrier magnetic tunnel junctions

open access: yes, 2020
© 2014 Elsevier B.V. All rights reserved. The spin-polarized tunnel conductance and tunnel magnetoresistance (TMR) through a planar asymmetric double-barrier magnetic tunnel junction (DBMTJ) have been calculated using quasi-classical model.

Ferroelectric Behavior of Micro‐ to Submicron‐Scale HZO Capacitors: Impact of the Perimeter‐to‐Area Ratio

open access: yesAdvanced Electronic Materials, EarlyView.
Using C‐AFM, W/HZO/p‐Ge capacitors with areas down to 0.26 µm2 are investigated. Frequency‐dependent voltage ramps reveal switching currents that confirm complete polarization reversal across the entire electrode area, while PUND enables reconstruction of P–V loops.

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Antiaromaticity‐Driven Enhancement of Single‐Molecule Electrical Conductance by s‐Indacene Molecular Bridges

open access: yesAngewandte Chemie, EarlyView.
Within the same molecular length scale, antiaromatic s‐indacene exhibits a marked increase in conductance compared to its aromatic benzodithiophene counterpart. Notably, the inherently small HOMO–LUMO gap of antiaromatic systems maintains a certain level of conductance even in the presence of cross‐conjugation.
