摘要

层状Cr-硫化物化合物构成了具有丰富晶体相及其磁性质 diverse 的材料体系，其中许多相仅被预测而未被实验验证。本文展示了通过金属有机化学蒸发(Vapor deposition, MOCVD)合成的CrS2未报道的晶体相——失眼八面体(1T $'$ ）结构。我们实现了对1T $'$ 或1T相CrS2的可调性合成。通过偏振拉曼光谱、密度泛函扰动理论(DFPT)以及扫描电子衍射(4D-STEM)鉴定了晶体结构。4D-STEM揭示，1T $'$ 晶体从最初形成的动力学优先1T相生长，随后转化为热力学稳定的1T $'$ 相。磁光 Kerr成像显示，1T $'$ CrS2晶体在低温下表现出软磁性。我们的MOCVD生长方法实现了具有长程磁有序的2D CrS2复杂相，为实现面向逻辑存储和自旋电子学的可缩放2D磁性材料奠定了基础。
