What is the poisson ratio of GeTe?

The Poisson's ratio of germanium telluride (GeTe) typically ranges from approximately 0.25 to 0.35, depending on the specific conditions and phase of the material. This ratio indicates how much the material deforms laterally when subjected to axial stress. Due to its phase-change properties, GeTe's mechanical characteristics, including Poisson's ratio, can vary with temperature and structural modifications.
