X-ray Diffraction and Electrical Transport Imaging of Superconducting Superhydride (La,Y)H10
Abdul Haseeb Manayil Marathamkottil, Kui Wang, Nilesh P. Salke +9
We report the synthesis and characterization of (La0.9Y0.1)H10 superhydrides exhibiting coexisting cubic Fm-3m and hexagonal P63/mmc clathrate phases observed over the pressure ran…
Evidence for Near Ambient Superconductivity in the Lu-N-H System
Nilesh P. Salke, Alexander C. Mark, Muhtar Ahart +1
The recent report of superconductivity in nitrogen-doped lutetium hydride at near-ambient pressures and temperatures has attracted great attention but also continuing controversy.…
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…
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…
Road to Room-Temperature Superconductivity: Tc above 260 K in Lanthanum Superhydride under Pressure
Russell J. Hemley, Muhtar Ahart, Hanyu Liu +1
The use of high pressure to realize superconductivity in the vicinity of room temperature has a long history, much of it focused on achieving this in hydrogen rich materials. This…
