论文摘要
通过精确的X射线衍射技术与低温极化THZ红外光谱和准确的磁转运测量进行了精确的X射线衍射技术进行了YBB12的高质量单域晶体的研究。首次证明，这种原型强度相关的系统具有金属构造器过渡到具有金属费米表面（Science 362，65-69（2018）和同上362，32-33（2018））的神秘介电基态状态实际上是一种无差的化合物。因此，在冷却后，研究了发现的动态电荷条纹的构型变化，因此得出结论，有利于穿透YBB12半导体矩阵的丝状电子结构的不同模式之间的交叉。我们认为，YBB12中的条纹的发现是基本的，阐明了近托绝缘子中异国介电状态的性质。
The studies of high-quality single-domain crystals of YbB12 were carried out by the precise x-ray diffraction technique in combination with the low temperature polarized THz - infrared spectroscopy and accurate magnetotransport measurements. It has been shown for the first time that this archetypal strongly correlated system with a metal-insulator transition to a mysterious dielectric ground state with a metal Fermi surface (Science 362, 65-69 (2018) and ibid 362, 32-33 (2018)) is actually a heterogeneous compound in the regime of electronic phase separation. Changes in the configuration of the discovered dynamic charge stripes are investigated upon cooling, as a result, a conclusion is drawn in favor of a crossover between different patterns of the filamentary electronic structure penetrating the semiconducting matrix of YbB12. We argue that the discovery of stripes in YbB12 is fundamental, elucidating the nature of exotic dielectric state in Kondo insulators.
