Understanding and Designing Phase Change Materials: Insights From Atom Probe Tomography

Advanced Science, EarlyView.
Atom probe tomography can distinguish metallic, covalent, and metavalent bonds based upon their bond rupture; in particular, the probability to form more than one ion (PME) in laser‐assisted field evaporation. These findings open new avenues in understanding and designing phase change materials (PCMs) since they allow quantification of bonds in solids ...

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors

Advanced Science, EarlyView.
This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

Giant tunability of superlattice excitations in chiral Cr1/3TaS2

npj Quantum Materials
Layered chalcogenides are superb platforms for exploring tunable functionality and the impact of external stimuli, and when intercalated with metal atoms, there are opportunities to reveal unique guest–host interactions. One barrier to greater control of

Tunable p–p Interactions Along Linear Chains Control Metavalent Bonding in Chalcogenide Heterostructures

Advanced Science, EarlyView.
Substitution of Sr at the Pb site within an atomic plane of PbTe perturbs the p–p hopping network. Since Sr does not support the p–p interaction key to metavalent bonding along (‐Pb‐Te‐) chains, long‐range electronic charge transfer in response to displacement of Pb is stalked at the Sr site.

Suppressing Morphological and Energetic Disorder in Copper Antimony Sulfide‐based Hole‐Transporting Materials via Ligand–Precursor Engineering for Efficient and Stable Perovskite Solar Cells

Advanced Science, EarlyView.
Sulfur‐precursor and ligand engineering regulate the nucleation, morphology, and energetic disorder of CuSbS2 nanocrystals for dopant‐free inorganic hole‐transport layers in perovskite solar cells. Thiourea‐assisted synthesis combined with optimized OAm/OAc coordination suppresses excessive anisotropic growth, enabling mixed plate‐like/quasi‐spherical ...
