Terahertz spectroscopic characterization of Ge <sub>3</sub> Sb <sub>2</sub> Te <sub>6</sub> compounds for active applications
Using THz time-domain spectroscopy, we measure the refractive index and conductivity of Ge 3 Sb 2 Te 6 in the THz, which exhibits lower losses throughout the metal-to-insulator transition and higher thermal robustness than the commonly used Ge 2 Sb 2 Te 5 .
