The new,lambda, phase exhibits an exceptionally wide range of pressure stability from below 1 to 140 GPa, overlapping nine other known phases. On heating, its transformations are different to those ...

A high-pressure study of a black phosphorus crystal establishes a rich phase diagram, including Weyl semimetal and superconducting states, Lifshitz-type semiconductor–semimetal transitions, and two ...

They explored a large pressure range from 1.2 to 1.9 million times normal atmospheric pressure, and saw the formation of a new nitrogen phase at approximately 1.5 million times normal atmospheric ...

An international team co-led by Ho-Kwang Mao and Huiyang Gou from Center for High Pressure Science and Technology Advanced Research (HPSTAR) and Yansun Yao from University of Saskatchewan discovered ...
