Herein, the synthesis of 2H‐1T′ WS2‐ReS2 heterophase junctions with high‐quality interface structure via a hydrogen‐triggered one‐pot growth approach is reported. Sequential introduction of hydrogen during growth system, which acts as a "switch" to selectively turn off the growth of ReS2 ...
Stable metallic 1T-WS2 nanoribbons with zigzag chain superlattices, highly stabilized by ammonia-ion intercalation, are produced using a facile bottom-up process. The atomic structure of the nanoribbons, including W-W reconstruction and W-S distorted octahedral coordination, results in distinctive electri...
研究结果表明:1T相的引入有助于提高WS2的复介电常数,进而显著提升WS2的微波吸收性能,在石蜡基质中吸波剂含量为35 wt%的情况下1T@2H WS2最高微波吸收强度可达-47.1 dB,是纯2H-WS2的15倍,对应的有效吸收带宽为5.2 GHz;该研究结果将为通过晶相调控提升材料微波吸收性能,开发新型吸波材料提供实验依据。2)强磁场下1T...
2024 Elsevier B.V.Two-dimensional transition metal dichalcogenides (TMDs) such as MoS2 and WS2 have traditionally been used, but Group-10 TMDs have recently attracted attention due to their small and tunable band gap and high mobility. This paper investigates the impact of vacancy and strain on...

(2H-WS2). Suchαsdistribution is thus about twice as wide as that found for the binding energy,Eb, indicating that the response to strain is the key property in determining the structure of possible vdWHs. We consistently find the di-chalcogenides to be stiffer than the halides, withαs...
范德华异质结构(vdWHs)如GaSe/MoSe2、MoTe2/MoS2、MoS2/WS2和WS2/BP等,能够克服传统异质结构的晶格和加工限制,为开发高性能2D vdWH太阳能电池和光电二极管提供了方向。然而,2D vdWH光伏器件的光吸收效率低,且其异质界面中存在电子/空穴陷阱,整体器件的灵敏度和响应速度仍有待提升。量子点(QD)作为一种强光吸收剂...
