AI总结:

本文采用NaCl/KCl共晶熔盐助熔剂法成功生长出尺寸为5×4×0.1 mm$^3$的1T-VSe$_2$单晶,并通过多种表征手段确认其成分、晶向和相结构,同时观察到约104 K处由电荷密度波引起的电阻率相变。

摘要:

VSe$_2$是一种极具应用前景的范德瓦尔斯(vdW)材料,可用于电子学、自旋电子学和光电子学领域。本文报道了利用NaCl/KCl共晶熔盐助熔剂法生长1T-VSe$_2$单晶的结果。所生长的VSe$_2$单晶典型尺寸为5×4×0.1 mm$^3$。通过能量色散X射线光谱法检测了晶体的元素组成和均匀性,结果与VSe$_2$的化学计量比一致。通过X射线衍射确定了晶体的[001]晶向。拉曼测量证实形成了1T相的VSe$_2$。变温电阻率测量显示,由于电荷密度波相的形成,在约104 K处出现相变。

英文摘要:

VSe$_2$ is a highly promising van der Waals (vdW) material for applications in electronics, spintronics, and optoelectronics. Here, we report single crystal growth of 1T-VSe$_2$ by flux method using eutectic of NaCl/KCl molten salt. The typical size of as-grown VSe$_2$ single crystals is 5 $\times$ 4 $\times$ 0.1~mm$^3$. The elemental composition and homogeneity of the crystals were examined by energy dispersive x-ray spectroscopy, which is consistent with the stoichiometric ratio of VSe$_2$. The crystallographic [001] direction has been determined by x-ray diffraction. Raman measurement confirms that the 1T phase of VSe$_2$ has been formed. Temperature-dependent resistivity measurement exhibits a transition around 104 K due to the formation of the charge density wave phase.
