High pressure phase transition in TiOCl and TiOBr
What is it about?
The filling of the Mott–Hubbard gap in TiOCl and TiOBr above a critical pressure Pc is observed, concomitant with a structural phase transition.
Why is it important?
Above Pc a mixture of the ambient-pressure orthorhombic Pmmn phase and a dimerized, monoclinic P21/m phase does exist.
