Phase transitions of β-ZnTe(en)_0.5 under hydrostatic pressure

This dataset contains IR spectra of β-ZnTe(en)0.5, a novel material that consists of alternating layers of two-monolayer-thick zinc telluride (ZnTe) and ethylenediamine (en). Using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy, this study investigated the structural response of β-ZnTe(en)0.5 to applied hydrostatic pressure. Pressure-induced phase transitions were observed at 2.1 GPa and 3.3 GPa. IR spectroscopy revealed abrupt changes in NH2 and CH2 vibrational modes corresponding to the phase transitions.
