Sequential Polymerization of Nitrogen at High Pressures

open access: yesChemistry–Methods, EarlyView.
Polynitrogen anions, including N2, N4, N6 rings, N18 rings, and N chains, form under high pressure. These anions exhibit unique bonding structures that are stabilized in such conditions. Detailed information regarding their formation and properties is available in the article.

Foreword: Focus on Superconductivity in Semiconductors

open access: yesScience and Technology of Advanced Materials, 2008
Since the discovery of superconductivity in diamond, much attention has been given to the issue of superconductivity in semiconductors. Because diamond has a large band gap of 5.5 eV, it is called a wide-gap semiconductor.

Superconducting Lithium Hydride in a Chemical Capacitor Setup: A Theoretical Study

open access: yesChemPhysChem, EarlyView.
Metallization of bulk lithium hydride has never been achieved through pressure alone. Single‐layer lithium hydride sandwiched between two support layers may resist hole doping up to substantial levels, forming a two‐dimensional metal (Fermi surface shown).

Vapor Deposition of Polymer Structures: From 2D Surface Coatings and Surface Microstructures to 3D Building Blocks and Structural Monoliths

open access: yesMacromolecular Rapid Communications, EarlyView.
This review discusses the progress of vapor‐deposited polymer structures, from simple thin films and surface microstructures to complex 3D architectures and monoliths. It covers fabrication methods, polymerization mechanisms, and processes for fabricating these structures. The applications of these polymers are discussed, focusing on device integration

High‐throughput calculation of large spin Hall conductivity in heavy‐metal‐based antiperovskite compounds

open access: yesMaterials Genome Engineering Advances, EarlyView.
The present work establishes high‐throughput database (more than 4500 structures) of SHC in antiperovskites and screens 295 structurally stable compounds and identifies 24 compounds with intrinsic SHC exceeding 500 (ℏ/e) (Ω⁻1 cm⁻1), which is crucial for designing future electric and spintronic devices.

High throughput characterization method of electrical and phonon properties by dielectric resonant spectroscopy

open access: yesMaterials Genome Engineering Advances, EarlyView.
In conventional theories, electron‐phonon relaxation time τe‐p ${\tau }_{e\mbox{-}p}$—the average interval between two consecutive electron‐phonon collisions—is assumed to be independent of electron density. In this study, we establish a new relationship of τe−p=C∗·T−1·n−1/3 ${\tau }_{e-p}={C}^{\ast }\mathit{\cdot }{T}^{-1}\mathit{\cdot }{n}^{-1/3 ...
