Irradiation‐Induced Spin Bath Evolution and as‐Grown Hydrogen Defects in CVD Diamond Revealed by NV‐Based DEER Spectroscopy

open access: yesAdvanced Functional Materials, EarlyView.
Here, we provide the reader with the current state of the art in the fabrication of high‐T2‐coherence diamond, optimized through the use of double electron–electron resonance (DEER) spectroscopy. We reveal the main as well as yet unidentified spin defects, the reduction of which is essential for reducing the spin bath and fabricating materials for ...

Chemical State Detection and Charge Transfer in Complex Oxide Heterostructures via In Situ Auger Electron Spectroscopy

open access: yesAdvanced Functional Materials, EarlyView.
In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

open access: yesAdvanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

From teacher quality to teaching quality: Instructional productivity and teaching practices

open access: yesEconomics of Education Review
This paper estimates the causal effects of math instructional time on student achievement using within-student variation across math topics in the TIMSS 2011 data. Based on the assessment’s detailed measurement of math skills, it shows that each weekly hour of math instruction increases student test scores by 4.3% of a SD.

Si‐Doped Nanocrystalline Diamond as Highly Sensitive Luminescence Thermometer for the Physiological Temperature Range

open access: yesAdvanced Functional Materials, EarlyView.
In this work, diamonds with negative charged silicon‐vacancy (SiV−) centers have been designed for use as thermometers in biomedical applications. Multiparametric analysis of the emission characteristics of the SiV− centers provides extraordinary sensitivity for temperature detection in the physiological temperature range.

Bridging Polymer Brushes and Coatings Through Ultra‐Thick Growth by Surface‐Initiated Photoiniferter Polymerization

open access: yesAdvanced Functional Materials, EarlyView.
Surface‐initiated photoiniferter‐mediated polymerization (SI‐PIMP) enables the controlled growth of UHMW polymer brushes with multi‐micrometer thicknesses, bridging conventional brushes and bulk‐like coatings. UHMW brushes are synthesized through a controlled/living process; they provide low friction and enhanced wear resistance under aqueous ...
