Crystal Structure and Phonon Density of States of FeSi up to 120 GPa
Ravhi S Kumar, Han Liu, Quan Li +9
The strongly correlated material FeSi exhibits several unusual thermal, magnetic, and structural properties under varying pressure-temperature (P-T) conditions. It is a potential t…
Structure and equation of state of from x-ray diffraction to megabar pressures
Alexander C. Mark, Muhtar Ahart, Ravhi Kumar +7
Pressure is a unique tuning parameter for probing the properties of materials and has been particularly useful for studies of electronic materials such as high-temperature cuprate…
X-ray Diffraction and Equation of State of the C-S-H Room-Temperature Superconductor
Anmol Lamichhane, Ravhi Kumar, Muhtar Ahart +10
X-ray diffraction indicates that the structure of the recently discovered room temperature carbonaceous sulfur hydride (C-S-H) superconductor is derived from previously established…
Hot Hydride Superconductivity above 550 K
A. D. Grockowiak, M. Ahart, T. Helm +9
The search for room temperature superconductivity has accelerated dramatically in the last few years driven largely by theoretical predictions that first indicated alloying dense h…
Characterization and decomposition of the natural van der Waals heterostructure SnSb2Te4 under compression
Juan A. Sans, Rosario Vilaplana, E. Lora Da Silva +16
This joint experimental and theoretical study of the structural, vibrational and electrical properties of rhombohedral SnSb2Te4 at high pressure unveils the internal mechanisms of…
New high-pressure phase and equation of state of Ce2Zr2O8
D. Errandonea, R. S. Kumar, S. N. Achary +4
In this paper we report a new high-pressure rhombohedral phase of Ce2Zr2O8 observed from high-pressure angle-dispersive x-ray diffraction and Raman spectroscopy studies up to nearl…
