Impact of the Schottky Barrier and Contact-Induced Strain Variations inside the Channel on the Electrical Behavior of Monolayer MoS<sub>2</sub> Transistors. [PDF]

open access: yesSmall Sci
This article reports a multiscale investigation of monolayer MoS2 field‐effect transistors, revealing a source/drain Schottky barrier of ≈0.21 eV and contact‐induced strain variations inside the channel. The impact of strain inhomogeneities on the electron effective mass (meff) distribution and their implications on carrier mobility and contact ...

Fenton-like Reactivity on Fe<sub>3</sub>O<sub>4</sub> Nanozymes Driven by Charge Transfer and Interfacial Water. [PDF]

open access: yesSmall
In magnetite nanozymes, subsurface Fe2⁺ donates electrons to H2O2, forming fleeting Fe(IV)═O and •OH species. The process couples charge flow, water‐mediated reactivity, and nanoparticle oxidation in a dynamic Fenton‐like cycle. Abstract Magnetite (Fe3O4) nanoparticles, widely recognized as inorganic nanozymes due to their enzyme‐like catalytic ...

Defect‐Engineering by Solvent Mediated Mild Oxidation as a Tool to Induce Exchange Bias in Metal Doped Ferrites

open access: yesSmall Methods, Volume 7, Issue 11, November 16, 2023., 2023
Inducing defects in the crystal lattice is a promising strategy for tuning chemical‐physical properties of nanoparticles (NPs). The introduction of lattice defects in substituted spinel ferrite NPs, performed by mild oxidation, allows to induce magnetic features that cannot be otherwise observed when the same nanomaterials are obtained by standard ...

Detecting Magnetic Permeability and Electrical Conductivity Fluctuations in Metallic Ferromagnetic Sheets through the Shielding Effect

open access: yesphysica status solidi (b), Volume 259, Issue 6, June 2022., 2022
Herein, a method for fast detection of fluctuations in structural and functional properties in metallic elements is presented. A particular application of mechanical stress in steel rail tracks is included. In this report, a method is proposed for determining the fluctuations of physical and structural properties in metallic ferromagnetic samples by ...

Further Evidence of High Intensity During the Levantine Iron Age Anomaly in Southwestern Europe: Full Vector Archeomagnetic Dating of an Early Iron Age Dwelling From Western Spain

open access: yesJournal of Geophysical Research: Solid Earth, Volume 126, Issue 9, September 2021., 2021
Abstract We report an archeomagnetic study from the Early Iron Age archeological site of Cerro de San Vicente (Salamanca, Spain). The studied materials were sampled from one roundhouse and its central fireplace, a surrounding burnt floor, and slags with a twofold objective.

Oligothiophene‐Based Phosphonates for Surface Modification of Ultraflat Transparent Conductive Oxides

open access: yesAdvanced Materials Interfaces, Volume 7, Issue 12, June 23, 2020., 2020
Self‐assembly of functional molecules that have an intrinsic dipole moment is often used to engineer charge transportation in optoelectronic devices. The present work demonstrates how aromatic oligothiophene molecules on transparent conductive oxides affect the work function depending on the anchoring group's position with respect to the organic moiety,
