Spectroscopic and structural measurements often give conflicting results about the role of disorder in determining the properties of energy materials. A hybrid neutron scattering technique is used to measure atomic correlations in time and space for cubic GeTe, revealing that anisotropic elastic interactions mimic disorder but the time-averaged structure is crystalline.

揭示能源材料中局部原子无序的起源

关于无序在确定能源材料特性中的作用，光谱和结构测量通常会得出相互矛盾的结果。混合中子散射技术用于测量立方 GeTe 的时间和空间原子相关性，表明各向异性弹性相互作用模拟无序，但时间平均结构是结晶的。
