MoS2 (2H phase) is a semiconductor with an indirect band gap of 1.2 eV. Monolayer MoS2 has a band gap of ~1.8 eV. Molybdenum Disulfide is used for example as a photodetector and transistor. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers.

2018年8月3日 · Here, we develop a simple yet effective method, cyclic voltammetry, to successfully tune the 2H/1T phase transition of multilayer MoS 2 nanosheets without using intercalation species.

MoS2 is Molybdenite structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two MoS2 sheets oriented in the (0, 0, 1) direction. Mo4+ is bonded to six equivalent S2- atoms to form …

2022年11月3日 · In the present work, 2H-MoS2 nano-structures are synthesized in the exfoliated form by a facile hydrothermal synthesis route and are studied as electrode material for electrochemical devices.

2024年12月2日 · The 2H-MoS 2 is a semiconductor with a direct bandgap of ~1.9 eV, whereas the 1T-MoS 2 is metallic in nature. In consistent with the electronic properties, the ultraviolet–visible (UV) visible spectroscopy studies confirm that no visible absorption peaks are observed in metallic 1T-MoS 2.

As shown in the Raman spectra (Figure 1 2a), the pristine 2H-MoS2 presents four main characteristic peaks at 282, 380, 406, and 450 cm −1 that correspond to the E1g, E ...

2025年1月1日 · In this work, first of all, 2H–MoS 2 is intercalated through PPy (MoS 2-PPy), then assembles the heterostructure (MoS 2-PPy@Ti 3 C 2 T x) and maintains the 2H phase throughout the entire process, ensuring the phase stability of the material. The interlayer spacing is widened after PPy-intercalation.

2024年10月24日 · Herein, we delve into the behavior of strained bilayer molybdenum disulfide (2L-MoS 2) transferred onto a nanocone-patterned substrate. An intriguing observation is the emergence of unexpected vertical ferroelectricity in MoS 2, irrespective of whether it was prepared using chemical vapor deposition or mechanical exfoliation from the bulk crystal.

Here, we employ the common hydrothermal method, followed by an additional solvothermal method to construct an uncommon molybdenum disulfide with two crystal forms of 1T and 2H to improve catalytic properties.

2017年8月18日 · Here, we demonstrate the one-step preparation of a highly stable 2H-MoS 2 dispersion via solvent thermal treatment in polar solvents using Li-intercalated MoS 2.
