Researchers are increasingly drawn to WSe2 due to its wide-ranging applications in electronic, optoelectronic, and catalytic materials. Like other transition metal dichalcogenides, it has different polymorphs, viz., 1T, 1T ', and 2H phases. A hexagonal close-packed layer-type structure of 2H-WSe...
While some of the other MX2 materials can be converted to the 1T′ phase by intercalation or strain, the added complexity makes it difficult to prove the QSH state20. WSe2, the material chosen for the present study, exhibits a hexagonal 2H structure in the bulk, which is of great ...
a stable Sn-doped metal phase tungsten selenide (1T-WSe2-Sn) was elaborately fabricated in situ by a simple calcination technique. N-doping was introduced by employing chitosan as precursor and nanoreactor, the Sn-doping induces 1T

Sn-doped induced stable 1T-WSe2 nanosheets entrenched on N-doped carbon with extraordinary half/full sodium/potassium storage performance At present, there have been some reports on the application of metal phase selenide (1T-MSe2) in the field of energy storage. In this manuscript, a stable ...
The monolayer 1T′-WSe2 was found to be metastable, and can transform into 2H phase under post-annealing procedure. The phase transition temperature of 1T′-WSe2 grown on BLG is lower than that of 1T′ phase grown on 2H-WSe2 layers. This thermo-driven crystalline phase transition makes ...
当将其构筑成异质结时,界面间的相互作用可以改变原光电性质或产生新的性质,是二维材料光电子器件功能控制的重要手段.利用机械剥离法制备WSe2/GeS异质结,通过发光光谱研究异质结层间激子的光学性质.结果表明:p型GeS与弱n型WSe2构筑成异质结时会产生新的层间激子.与GeS和WSe2的荧光发射强度相比,异质结的层间激子...
不同于具有高对称2H结构的VI族TMDs材料(如MoS2和WSe2),VII族TMDs(如ReS2和ReSe2)材料具有低对称的1T'结构。这种晶格结构对称性的降低赋予了这类材料独特的二维面内各向异性光学和电学性质,使其在场效应晶体管、光电探测器和新概念器件等方面具有很大的应用潜力。然而,因VII族TMDs材料的结构更加复杂,其制备和性质...
