Naturally occurring or synthetically grown semiconducting 2H-MoS2 can either be converted into metallic 1T-MoS2, or various dopants may be introduced to modulate the electronic band gap of...

2023年3月16日 · Figure 6F–I shows the SAED patterns of a MoS 2 SIB electrode at different states of discharge. They include 2H MoS 2, a heterogeneous structure of 2H and 1T MoS 2, 1T MoS 2, and the distorted 1T’ structure with Mo zigzag chains.

2024年1月20日 · Additionally, the Selected Area Electron Diffraction (SAED) patterns for both materials revealed crystalline structures characterized by diffraction spots indicative of the hexagonal lattice structures of 2H-MoS 2 and the coexistence of 1T and 2 H phases in 1T@2H-MoS2, further supporting the phase purity and crystalline nature of the ...

2014年12月1日 · Simulated SAED patterns of 1T MoS 2 at various x- and y-tilt angles. Both monolayer and multi-layer patterns contain diffraction spots that vanish with tilt, primarily for the band of spots perpendicular to the tilt axis. Linear intensity scaling; scale bars are 0.24 Å −1.

2018年12月7日 · 1T-MoS 2, metallic in nature with a high carrier concentration, meets the resistance requirement to exhibit 2D superconductivity. The 1T phase is generally prepared by structural modification...

2019年6月15日 · Fig. 6 (c) shows the SAED patterns of the MoS 2 films of 400 °C. The SAED pattern depicts a mixed 1T-2H heterogeneous phase of MoS 2 with polycrystalline nature. (004) and (100) plane (presented in red color) of the 2H phase and (110) and (003) plane (presented in blue color) of 1T phase are visibly prominent in the SAED pattern [30, 31].

A phase transfer from 2H to 1T/2H MoS2 with the ferromagnetic spin-polarization of SA Fe-N-C occurs during the sodiation/desodiation process, which significantly enhances the Na+ storage...

2021年8月1日 · The selected area electron diffraction (SAED) pattern taken from the marked region in Fig. 1 a shows diffraction rings, which reveals the polycrystallinity of the 1T/2H-MoS 2 /Ni bonded to the sidewall of CNT owing to the nanoscale assembly of different dimension crystallites (Fig. S2c) [18, 21].

Optimized parameters of DFT calculations, the characterizations of commercial MoS 2 powders (including XRD, SEM, XPS, and BET tests), TEM images of 1T- and 2H-phase MoS 2, SAED images of 1T-phase MoS 2, and the corresponding electrochemical performances of these three electrodes in supercapacitors and LIBs

The SAED patterns for 2H, heterogeneous 1T/2H and 1T are identical, varying only in intensity but exhibiting the same reflection indexes. 75 Only the distorted 1T’ displays a different Laue spot arrangement (Figure 6I). Between the high magnification microscopy images and the SAED patterns, the local phase can be confirmed.
