Experimental and theoretical study of β-As2Te3 under hydrostatic pressure

We report a joint experimental and theoretical high-pressure study of the structural and vibrational properties of tetradymite-like (R3m) β-As2Te3. Two samples have been characterized by angle-dispersive synchrotron powder X-ray diffraction and Raman scattering measurements under hydrostatic conditi...
