Synthesis, structure and electric conductivity of higher hydrides of ytterbium at high pressure

Tomasz Jaronn, Jianjun Ying, Marek Tkacz +4

While most of the rare earth metals readily form trihydrides, due to increased stability of the filled 4f electronic shell for Yb(II), only YbH, formally corresponding to…

Novel rhenium carbides at 200 GPa

Saiana Khandarkhaeva, Timofey Fedotenko, Maxim Bykov +7

Laser heating of rhenium in a diamond anvil cell to 3000 K at about 200 GPa results in formation of two previously unknown rhenium carbides, hexagonal WC-type structured ReC and or…

Novel Superstructure-Phase Two-Dimensional Material 1-VSe at High Pressure

Raimundas Sereika, Changyong Park, Curtis Kenney-Benson +11

A superstructure can elicit versatile new properties of materials by breaking their original geometrical symmetries. It is an important topic in the layered graphene-like two-dimen…

The Effect of Pressure on the Negative Thermal Expansion of Solid Methane

Yu. A. Freiman, V. V. Vengerovsky, Alexander F. Goncharov

The effect of pressure on the thermal expansion of solid CH is calculated for the low temperature region where the contributions from phonons and librons can be neglected and o…

Intermolecular coupling and fluxional behavior of hydrogen in phase IV

Alexander F. Goncharov, Irina Chuvashova, Cheng Ji +1

We performed Raman and infrared (IR) spectroscopy measurements of hydrogen at 295 K up to 280 GPa at an IR synchrotron facility of SSRF. To reach the highest pressure, hydrogen was…
