Metallic Hydrogen Sublattice and Proton Mobility in Copper Hydride at High Pressure
Thomas Meier, Florian Trybel, Giacomo Criniti +9
Atomic and electronic structures of Cu2H and CuH have been investigated by high pressure NMR spectroscopy, X-ray diffraction and ab-initio calculations. Metallic Cu2H was synthesiz…
Narrowing band gap chemically and physically: Conductive dense hydrocarbon
Takeshi Nakagawa, Caoshun Zhang, Kejun Bu +14
Band gap energy of an organic molecule can be reduced by intermolecular interaction enhancement, and thus, certain polycyclic aromatic hydrocarbons (PAHs), which are insulators wit…
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…
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 polymeric nitrogen allotrope with the black phosphorus structure
Dominique Laniel, Bjoern Winkler, Timofey Fedotenko +6
Studies of polynitrogen phases are of great interest for fundamental science and for the design of novel high energy density materials. Laser heating of pure nitrogen at 140 GPa in…
Aromatic Hexazine [N6]4- Anion Revealed in the Complex Structure of the High-Pressure Potassium Nitride K9N56
Dominique Laniel, Florian Trybel, Yuqing Yin +13
Recent high-pressure synthesis of pentazolates and subsequent stabilization of the aromatic [N5]- anion at atmospheric pressure had an immense impact on nitrogen chemistry. Here, w…
