High pressure structural change and superconductivity in jacutingaite

The result of our collaboration with the group of Prof. Yanpeng Qi at ShanghaiTech University has just been published in npj Quantum Materials. Our work reveals that Pt2HgSe3 (jacutingaite) transforms to a monoclinic structure (space group Pc), above 55 GPa and at the same time becomes a superconductor.

Our paper on Pt2HgSe3 has been published in Nano Letters

Pt2HgSe3 is a layered, van der Waals mineral, called jacutingaite. It was discovered in 2008 in Brazil [1] and the monolayer has been predicted to be a large gap topological insulator [2]. Our group has been able to detect signatures of the predicted topological edge states, within a bulk gap that is larger than 100 […]
