Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

Molecular Dynamics Study of Bamboo-like Carbon Nanotube Nucleation

, 2006
MD simulations based on an empirical potential energy surface were used to study the nucleation of bamboo-like carbon nanotubes (BCNTs). The simulations reveal that inner walls of the bamboo structure start to nucleate at the junction between the outer ...

Tuning D‐Band Center of Vanadium in Constructing Lattice‐Matched Coherent Heterostructure for Enhanced Sodium Storage

Advanced Functional Materials, EarlyView.
The coherent heterostructure and the strong stress field at the heterointerface upshift the d‐band center of vanadium toward the Fermi level, which effectively lowers the Na+ diffusion barrier, facilitates charge transfer and accelerates reaction kinetics.
