Observation of Conventional Near Room Temperature Superconductivity in Carbonaceous Sulfur Hydride
Hiranya Pasan, Elliot Snider, Sasanka Munasinghe +21
The phenomenon of high temperature superconductivity, approaching room temperature, has been realized in a number of hydrogen-dominant alloy systems under high pressure conditions1…
Metallic Hydrogen: Experiments on Metastability
W. Ferreira, M. Moller, K. Linsuain +4
Molecular hydrogen was pressurized in a diamond anvil cell at temperatures between 5 and 83 K. At a sufficiently high pressure, estimated to be between 477 to 491 GPa, hydrogen bec…
Pressure induced 3D strain in 2D Graphene
Nathan Dasenbrock-Gammon, Sachith Dissanayake, Ranga Dias
Two-dimensional (2D) materials such as graphene offer a variety of outstanding properties for a wide range of applications. Their transport properties in particular present a rich…
Second harmonic AC calorimetry technique within a diamond anvil cell
Nathan Dasenbrock-Gammon, Raymond McBride, Gyeongjae Yoo +2
Tuning the energy density of matter at high pressures gives rise to exotic and often unprecedented properties, e.g., structural transitions, insulator-metal transitions, valence fl…
Reply to "Comment on Nature 586, 373 (2020) by E. Snider et al."
Ranga P. Dias, Ashkan Salamat
In this paper, we respond to a recent criticism of our work on CSH, (1,2) raised by Hirsch and van der Marel on the arXiv (3). We point out that their non-peer reviewed critique (3…
Lower pressure phases and metastable states of superconducting photo-induced carbonaceous sulfur hydride
G. Alexander Smith, Ines E. Collings, Elliot Snider +9
Room-temperature superconductivity was recently discovered in carbonaceous sulfur hydride (C-S-H) close to 3\,Mbar. We report significant differences in the superconducting respons…
Standard Superconductivity in Carbonaceous Sulfur Hydride
Ranga P. Dias, Ashkan Salamat
The recently discovered room temperature superconductivity (RTSC) in carbonaceous sulfur hydride reveals the promise of a new superconducting technological era. Since the publicati…
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…
Towards high-throughput superconductor discovery via machine learning
Stephen R. Xie, Y. Quan, Ajinkya Hire +5
Even though superconductivity has been studied intensively for more than a century, the vast majority of superconductivity research today is carried out in nearly the same manner a…
Superconductivity to 262 kelvin via catalyzed hydrogenation of yttrium at high pressures
Elliot Snider, Nathan Dasenbrock-Gammon, Raymond McBride +6
Room temperature superconductivity has been achieved under high pressure in an organically derived carbonaceous sulfur hydride with a critical superconducting transition temperatur…
Carbon-Doped Sulfur Hydrides as Room-Temperature Superconductors at 270 GPa
S. X. Hu, R. Paul, V. V. Karasiev +1
To understand the most-recent experiment on room-temperature superconductivity in carbonaceous sulfur hydride (CSH) systems under high pressure, we have performed extensive stoichi…
Hole-Doped Room-Temperature Superconductivity in HSZ (Z=C, Si)
Yanfeng Ge, Fan Zhang, Ranga P. Dias +2
We examine the effects of the low-level substitution of S atoms by C and Si atoms on the superconductivity of HS with the structure at megabar pressure. The hole d…
Comment on: Observation of a first order phase transition to metal hydrogen near 425 GPa
Isaac F. Silvera, Ranga Dias
Loubeyre, Occelli, and Dumas (LOD) [1] claim to have produced metallic hydrogen (MH) at a pressure of 425 GPa, without the necessary supporting evidence of an insulator to metal tr…
Observation of the Wigner-Huntington Transition to Solid Metallic Hydrogen
Ranga Dias, Isaac F. Silvera
We have studied solid hydrogen under pressure at low temperatures. With increasing pressure we observe changes in the sample, going from transparent, to black, to a reflective meta…
