Tailoring Dielectric Relaxation and Charge Transport in Amorphous Ge-Te-Se Phase-Change Materials through Yttrium Incorporation

Surbhi Agarwal, Jiří Vacík, D. K. Dwivedi

The Te(1-x)(GeSe0.5)Yx (x = 0.05, 0.10, 0.15) alloys were prepared by a melt-quenching method and characterized using dielectric spectroscopy. The dielectric parameters and electri…
