Halogen Chains with One-Dimensional Semi-Metallic Electronic Structure and Peierls Physics in Polymorphs of Na4X5 (X = I, Br, Cl) Compounds
Yuqing Yin, Nityasagar Jena, Florian Knoop +16
Since the pioneering works of Peierls, one-dimensional materials have attracted great attention. Still, the synthesis of truly monoatomic chains remains elusive. In this study, we…
Polytypism of Incommensurately Modulated Structures of Crystalline Bromine upon Molecular Dissociation under High Pressure
Yuqing Yin, Andrey Aslandukov, Maxim Bykov +14
Polytypism of incommensurately modulated structures was hitherto unobserved. Here, we found the phenomenon in simple halogen systems of bromine and iodine upon molecular dissociati…
High-Pressure Synthesis of Seven Lanthanum Hydrides with a Significant Variability of Hydrogen Content
Dominique Laniel, Florian Trybel, Bjoern Winkler +12
The lanthanum-hydrogen system has attracted significant attention following the report of superconductivity in LaH10 at near-ambient temperatures and high pressures. Here, we prese…
Universal Hydrogen Bond Symmetrisation Dynamics Under Extreme Conditions
Thomas Meier, Florian Trybel, Dominique Laniel +5
The experimental study of hydrogen bonds and their symmetrisation under extreme conditions is predominantly driven by diffraction methods, despite challenges of localising or probi…
In-situ High Pressure Nuclear Magnetic Resonance Crystallography
Thomas Meier, Alena Aslandukova, Florian Trybel +5
Our recent developments in in-situ nuclear magnetic resonance (NMR) spectroscopy under extreme conditions led to the observation of a wide variety of physical phenomena not accessi…
High-Pressure Na3(N2)4, Ca3(N2)4, Sr3(N2)4, and Ba(N2)3 Featuring Nitrogen Dimers with Non-Integer Charges and Anion-Driven Metallicity
Dominique Laniel, Bjoern Winkler, Timofey Fedotenko +12
Charged nitrogen dimers are ubiquitous in high-pressure binary metal-nitrogen systems. They are known to possess integer formal charges x varying from one through four. Here, we pr…
Structure and composition of C-S-H compounds up to 143 GPa
Elena Bykova, Maxim Bykov, Stella Chariton +7
We synthesized two C-S-H compounds from a mixture of carbon and sulfur in hydrogen and from sulfur in mixed methane-hydrogen fluids at 4 GPa. X-ray synchrotron single-crystal diffr…
