2020年1月6日 · Here, we report the successful synthesis of (SnSe) 1.16 (NbSe 2) 2 single crystals and the discovery of superconductivity with an onset transition temperature of 5.3K. The misfit feature of structure is clearly revealed by high resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED).

2016年3月2日 · The selected-area electron diffraction (SAED) pattern (inset of Figure 1b) reveals a single crystalline phase of the as-synthesized nanobelts. Figure 1c shows the morphology of the MoS 2 /NbSe 2 hybrid nanobelts with a thicker size along the radial direction, compared to pure NbSe 2 nanobelts.

2022年10月1日 · In this paper, we conduct a study on a few-layer Nb 1+x Se 2 grown by MBE on SiO 2/Si substrates. A single crystal bulk 2H–NbSe2 sample grown by chemical vapor transport (CVT) was used as a reference. The MBE-grown material was characterized by X-ray photoelectron spectroscopy (XPS) and STM.
