论文摘要
通过X射线衍射研究了电荷密度波（CDW）状态中1T-TISE2的电子和晶体结构之间的相关性。三个反射家族用于SE中的原子位移和轨道不对称。发现两个不同的发作温度，TCDW和一个较低的T*指示性，用于发作平面外原子位移。 T*与最大的直流电阻率和提出的陀螺仪电子结构的发作相吻合。但是，找不到手性的迹象。根据Ti 3D和Se 4P状态，讨论了原子位移与运输特性之间的关系，而Ti 3d和Se 4P状态仅弱逐渐划分为CDW顺序。
The correlation between electronic and crystal structures of 1T-TiSe2 in the charge density wave (CDW) state is studied by x-ray diffraction. Three families of reflections are used to probe atomic displacements and the orbital asymmetry in Se. Two distinct onset temperatures are found, TCDW and a lower T* indicative for an onset of Se out-of-plane atomic displacements. T* coincides with a DC resistivity maximum and the onset of the proposed gyrotropic electronic structure. However, no indication for chirality is found. The relation between the atomic displacements and the transport properties is discussed in terms of Ti 3d and Se 4p states that only weakly couple to the CDW order.
