Structural transition of PETN-I to ferroelastic orthorhombic phase PETN-III at elevated pressures

Using powder x-ray diffraction and first-principles calculations, we provide evidence for a structural transition of PETN-I below 6 GPa to an orthorhombic phase of space group P 2 1 2 1 2 . The transition can be rationalized as shear-stress induced and ferroelastic, which involves a slight static di...
