Feb 12, 2019 · Here we demonstrate a direct solution-phase synthesis of the metastable distorted octahedral structure (1T’ phase) of WSe 2 not stabilised by charged species. We design a kinetically controlled...

Apr 15, 2021 · Here, we report a general synthetic method for the large-scale preparation of metastable 1T′-phase group VIB TMDs, including WS2, WSe2, MoS2, MoSe2, WS2xSe2(1−x) and MoS2xSe2(1−x).

May 21, 2018 · In this work, we show that single layers of WSe 2 can be prepared instead in the 1 T ′ phase, which is topological with a gap of 129 meV based on angle-resolved photoemission spectroscopy...

Jul 1, 2022 · Here, we demonstrate the synthesis of 1T′ WSe 2 on a substrate by a simple heating-up method using a single precursor, tetraethylammonium tetraselenotungstate [(Et 4 N) 2 WSe 4].

Dec 31, 2020 · Inspired by this discovery, SrTiO 3 (100) is chosen as substrate and WSe 2 monolayer is successfully grown in a 100% single 1T’ phase using the molecular beam epitaxial method.

Aug 26, 2024 · In this article, we synthesized a stable flower-like 1T′-WSe 2 nanosheet in a facile solvothermal process. We also tried to explore the structural details using the Rietveld …

Feb 12, 2019 · Access to metastable crystal phases is limited as their direct synthesis is challenging, restricting the spectrum of reachable materials. Here, we demonstrate the solution phase synthesis of the metastable distorted octahedrally coordinated structure (1T’ phase) of WSe 2 nanosheets.

Apr 27, 2022 · The Ag 2 Se NPs direct the growth of 1L–1T-WSe 2 nanosheets forming the quasi-monolayer hybrid nanosheets by lodging in the interlayer spaces of WSe 2 while the Ag 2 Se NPs being in a superionic conductor state diffuse rapidly and prevent the growth of piled-up multilayered WSe 2 nanosheets.

Here, we investigate the structural, electronic, optical, and excitonic properties of the 1T′ WSe 2 monolayer. Phonon dispersion analysis confirmed the thermodynamic stability of this system.

Feb 21, 2025 · Addressing the limited studies on temperature effects of 1T′-TMDCs, our research focuses on the crystal and electronic properties of epitaxial 1T′-WSe 2 monolayers grown on bilayer graphene (BLG) and SrTiO 3 (100) substrates at various temperatures.
