Single crystal diffraction of FeGe at low temperature

We measure high-resolution x-ray diffraction and diffuse scattering of FeGe single crystals at temperatures down to 2K. We investigate the structural evolution with temperature and study the formation of charge density waves.我们在低至2开尔文的温度条件下，对FeGe单晶体开展高分辨率X射线衍射（high-resolution X-ray diffraction）与X射线漫散射（diffuse scattering）测试。我们探究了该体系的结构随温度的演化行为，并研究了电荷密度波（charge density waves）的形成过程。
