Raman and X-ray diffraction analysis confirmed the polycrystalline growth of a few layers MoS2 on TiO2/Ti through their characteristic peaks. Field emission scanning electron microscopy...

Raman and X-ray diffraction analyses verified the growth of the dominant 1T-phase, which provides more active sites on the film. Electron microscope images exhibit the formation of long MoS2...

2018年10月15日 · The synthesis of 1T′ MoS2 monolayers with high phase purity allows us to characterize their intrinsic optical and electrical properties, revealing a characteristic in-plane anisotropy.

2018年4月2日 · We reveal that 1T′-MoS2 crystals feature a distorted octahedral coordination structure and are convertible to 2H-MoS2 following thermal annealing or laser irradiation.

Raman spectra of 2H-MoS 2 (black),1T-MoS 2 (green), and metal ion intercalated 1T-MoS 2 samples. [...] We show that intercalation of cations (Na⁺, Ca²⁺, Ni²⁺, and Co²⁺) into the interlayer region...

2018年8月20日 · Here we demonstrate a controllable and scalable 2H to 1T phase engineering technique for MoS2 using microwave plasma. Our method allows lithographically defining 1T regions on a 2H sample.

2019年3月1日 · The Raman spectra of 2H-MoS 2, 1T@2H-MoS 2 and 1T@2H-MoS 2 /Au (Fig. 2) exhibit two distinct peaks at 377.3 cm −1 and 402.4 cm −1, which correspond to the in-plane and out-of plane interaction Mo-S phonon mode E 2 g 1 and A 1g respectively.

2020年8月31日 · The substrate-dependent Raman enhancement distinctly demonstrates that calcination temperature for 1T-MoS 2 in air plays a significant role in determining the Raman enhancement of the probe molecules, which affects the internal structure of 1T-MoS 2 crystals and species of matter.

2019年7月17日 · Our SERS results demonstrate that 1T-MoS 2 significantly increases the Raman signal of probe molecules through efficient CT. (10) Furthermore, the obtained negatively charged 1T-MoS 2 layers feature the versatility to chemically modify the MoS 2 structures for potential sensing applications.

2018年8月20日 · We perform an in-depth structural characterization using high-resolution transmission electron microscopy (HR-TEM) and Raman spectroscopy. We also examine the evolution of photoluminescence (PL) spectra as a function …
