近年来，过渡金属二硫化物（TMD）材料在电子和光电子领域的应用前景广阔。它们的大部分性能与其丰富的结构相和相变密切相关。为了将来更多的实际应用，有必要对该材料体系的相变进行调整。在这里，我们通过适当的合金化证明了WxMo1−xTe2混相样品的相变调制。利用时域热反射法测量了与相结构和缺陷水平密切相关的c轴热导率。此外，在热输运和电输运性质中观察到相变引起的可调迟滞效应，并在拉曼光谱研究中被一致的迟滞所证实。这种迟滞效应可以应用于实现相变存储器件。此外，我们还提供了相图来说明复合材料。
Recently, transition metal dichalcogenide (TMD) materials have shown promise in electronics and optoelectronics applications. Most of their properties are closely related to their abundant structural phases and phase transitions. For more practical applications in the future, it is necessary to tune the phase transitions in this material system. Here, we demonstrate the modulation of phase transitions in miscible WxMo1−xTe2 samples by appropriate alloying. The temperature dependent thermal conductivity along the c-axis, which strongly relates to the phase structures and the defect level, has been measured using the time-domain thermoreflectance method. In addition, a tunable hysteretic effect, induced by phase transitions, is observed in both thermal and electrical transport properties and confirmed by the consistent hysteresis in the Raman spectroscopic study. This hysteretic effect can be applied to realize phase-change storage devices. Furthermore, we provide a phase diagram to illustrate the compositi...
