Nonreciprocal Charge Transport in an Iron‐Based Superconductor with Broken Inversion Symmetry Engineered by a Hydrogen‐Concentration Gradient

open access: yesAdvanced Science, EarlyView.
Concentration gradients can serve as a universal platform for breaking spatial inversion symmetry. We demonstrate this concept by observing nonreciprocal electrical transport—a sensitive probe of inversion‐symmetry breaking—in the iron‐based superconductor Sm1111 with an engineered hydrogen gradient.

Materials based on CdS/MgO nanocomposites applied in the photocatalytic hydrogen generation

open access: yesJournal of Materials Science: Materials in Engineering
The synergy between a semiconductor, such as CdS, and an insulator, such as MgO, was approached to improve the photocatalytic H2 evolution. Commercial MgO, nitrate magnesium and carbonate magnesium as Mg precursor of MgO were evaluated in the obtaining ...

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

open access: yesAdvanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Synergistic Pyro‐Phototronics and Structural Anisotropy in CsAg2I3/GaN Heterostructures for High‐Performance Polarization‐Sensitive UV Photodetectors

open access: yesAdvanced Science, EarlyView.
The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.

Symmetry Selective Resonances in Fe-MgO-ZnO-MgO-Fe

open access: yes
Abstract We propose the physics of symmetry-selective resonance of the ∆1 states in the Fe/MgO/ZnO/MgO/Fe heterostructures, that offers a broad landscape to design magnetic tun- nel junctions (MTJs). These MTJs yield a towering tunnel magnetoresistance (TMR) upto 3.5×104% with the resistance area (RA) product dipping down till a minimum of 0 ...

Proximity Ferroelectricity in Compositionally Graded Structures

open access: yesAdvanced Electronic Materials, EarlyView.
We perform the finite element modeling of the polarization switching in the compositionally graded AlN‐Al1‐xScxN and ZnO‐Zn1‐xMgxO structures and reveal the switching of spontaneous polarization in the whole structure in all these systems. The coercive field to switch is significantly lower than the electric breakdown field of the unswitchable AlN and ...
