A team led by Prof. Su Fuhai from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS), together with researchers from the Aerospace Information Research Institute, and the Center for High Pressure Science and Technology Advanced Research has investigated the nonequilibrium electron and phonon dynamics of the topological insulator Sb2Te3 under pressure and explored the ultrafast photophysics across the electronic topological and lattice structure transitions.
