On the Stability and Structural Dynamics of Metal Nanowires

, 2005
This article presents a brief review of the nanoscale free-electron model, which provides a continuum description of metal nanostructures. It is argued that surface and quantum-size effects are the two dominant factors in the energetics of metal ...

High‐κ Perovskite‐Like Ternary Niobium Oxide Dielectrics for 2D Electronics

Advanced Materials, EarlyView.
High‐κ dielectrics are vital for scaled electronics. Here, a family of 2D high‐κ perovskite‐like ternary niobium oxides is synthesized via a molten salt‐assisted method. Their integration into FETs and logic gates reveals superior switching characteristics, providing a fresh material platform and new insights for the advancement of high‐performance 2D ...

Li Incorporation Induces Surface Chemical Disorder in Solution‐Processed Cu2ZnSn(S,Se)4

Advanced Materials Interfaces, EarlyView.
Lithium incorporation into Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film semiconductors is highly beneficial for solar power conversion efficiencies, although directly visualising its impact on the absorber is difficult. Energy‐filtered photoemission electron microscopy measurements reveal lithium alloying induces surface chemical disorder of CZTSSe, highlighted ...

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.
