Universal diamond edge Raman scale to 0.5 terapascal: The implication to metallization of hydrogen
M. I. Eremets, V. S. Minkov, P. P. Kong +3
The recent progress in generating static pressures up to terapascal values opens opportunities for studying novel materials with unusual properties, such as metallization of hydrog…
Metallization of hydrogen
M. I. Eremets, P. P. Kong, A. P. Drozdov
In previous work,1 we showed that hydrogen metallizes in phase III at temperatures below ~200 K and at pressures near ~350 GPa. Here, we perform a detailed study of electrical cond…
Semimetallic molecular hydrogen at pressure above 350 GPa
M. I. Eremets, A. P. Drozdov, P. P. Kong +1
According to the theoretical predictions, insulating molecular hydrogen dissociates and transforms to an atomic metal at pressures P~370-500 GPa. In another scenario, the metalliza…
Comments on the claimed observation of the Wigner-Huntington Transition to Metallic Hydrogen
M. I. Eremets, A. P. Drozdov
In their recent work Dias and Silvera (Science 2017) claim to have observed the Wigner-Huntington transition of hydrogen to a metallic state (MH) at a pressure of 495 GPa at low te…
Low temperature phase diagram of hydrogen at pressures up to 380 GPa. A possible metallic phase at 360 GPa and 200 K
M. I. Eremets, I. A. Troyan, A. P. Drozdov
Two new phases of hydrogen have been discovered at room temperature in Ref.1: phase IV above 220 GPa and phase V above ~270 GPa. In the present work we have found a new phase VI at…
Nitrogen backbone oligomers
H. Wang, M. I. Eremets, I. Troyan +3
In contrast to carbon, which forms long polymeric chains, all-nitrogen chains are very unstable. Here we found that nitrogen and hydrogen directly react at room temperature and pre…
Transparent dense sodium
Y. Ma, M. I. Eremets, A. R. Oganov +6
Under pressure, metals exhibit increasingly shorter interatomic distances. Intuitively, this response is expected to be accompanied by an increase in the widths of the valence and…
