2018年4月25日 · Scanning transmission electron microscopy unambiguously reveals the 3R stacking mode of as-synthesized MoTe 2. Second harmonic generation measurement confirms the excellent odd/even layer-independent frequency conversion efficiency. Besides, the outstanding intrinsic infrared detection ability of as-synthesized 3R-MoTe 2 …

2021年7月28日 · From among the polytypes, the 3R-MoS 2 (rhombohedral) phase has attracted the most interest because of its thermodynamic stability, ABC stacking (as opposed to the AA′ of the more common 2H-MoS 2), and lack of inversion symmetry. These properties make it an excellent candidate for photonics, optoelectronics, and catalysis.

2024年2月15日 · Our findings highlight the crucial role of DWs in sliding ferroelectricity, suggesting a promising pathway for 3R-MoS 2 to serve as fundamental building blocks for programmable optoelectronic...

On top of the phase transition between the 2H and 1T ′ phase, it is also possible to obtain 3R MoTe 2 with proper precursor selection. In a recent study by Yang et al., MoCl 5 was adopted to...

2020年7月24日 · When Mo metal is used as a seed layer, semiconducting 2H-MoTe 2 is the only product. Conversely, MoO 3 leads to the preferential growth of metallic 1T′-MoTe 2. The control over phase growth...

在这里，通过合理地控制沉积温度和碲化速度，首次通过化学气相沉积法从MoCl 5前体中合成了高质量的2D 3R-MoTe 2薄片。 扫描透射电子显微镜清楚地显示了合成的MoTe 2的3R堆叠模式。

2018年6月27日 · Scanning transmission electron microscopy unambiguously reveals the 3R stacking mode of as‐synthesized MoTe2. Second harmonic generation measurement confirms the excellent odd/even...

To achieve this, the first direct synthesis of twisted 3R-stacked chiral molybdenum diselenide (MoSe2 ) spiral structures with specific screw dislocations (SD) arms is reported, via designing a...

2024年10月15日 · 在 2H 相 MoS₂ 中，晶体的六方对称性（D₃d 点群）允许电子在层内自由传输，层间的相互作用相对较弱，因而其电子态主要集中在层内形成的能带结构上。而在 3R 相 中，虽然其堆叠方式有所不同，但其整体对称性依然保持高，对电子结构的影响较小。

Scanning transmission electron microscopy unambiguously reveals the 3R stacking mode of as‐synthesized MoTe 2. Second harmonic generation measurement confirms the excellent odd/even layer‐independent frequency conversion efficiency. Besides, the outstanding intrinsic infrared detection ability of as‐synthesized 3R‐MoTe 2 is demonstrated ...
