Raman scattering investigation and symmetry analysis of ferroelectric/ferroelastic Sb5O7I polytype 2MA
The polytype 2MA (β-Sb5O7I) has the simplest acentric structure of the antimony oxideiodide family. It undergoes an antiferrodistortive phase transition at 438K and is both ferroelectric and ferroelastic below th...

Infrared and Raman study of Si2Te3
Results of ir and Raman investigations on trigonal layer-structured Si2Te3 single crystals are reported. The ir reflection spectrum withE⊥c exhibits seven reststrahl-like bands, whereas the corresponding spectrum...
