光电子能谱结合压力显微镜揭示了Rashba带的螺旋性与GeTe（111）的非挥发性铁电极化耦合。通过与密度泛函理论计算结果的比较，发现了一种新的表面Rashba带，并确定了一种散装Rashba带的指纹。
Photoelectron spectroscopy in combination with piezoforce microscopy reveals that the helicity of Rashba bands is coupled to the nonvolatile ferroelectric polarization of GeTe(111). A novel surface Rashba band is found and fingerprints of a bulk Rashba band are identified by comparison with density functional theory calculations.
