Abstract

X-ray photoelectron spectra of the [Mo₆Cl₈]Cl₄ cluster compound have been measured and discussed. For the interpretation of the valence band spectrum several SW Xα calculations have been performed. Comparison between calculated and experimental spectra illustrates the importance of covalent Mo-Cł bonding for the stability of the cluster.

The one-step reaction approach from syngas with hydrogen sulfide (CO/H₂/H₂S) over potassium (K) promoted Molybdenum disulfide (MoS₂) materials can provide alternatives for the synthesis of methanethiol (CH₃SH). However, the direct confirmation and determination of the real active nature of K-induced 2H and 1T′-MoS₂ for this reaction and the corresponding phase transformation behavior and origin of K-induced 2H-MoS₂ from/to 1T′-MoS₂ remains unclear. Herein, we proved at the atomic level the precise position of K over 1T′-MoS₂ and 2H-MoS₂ species using the technique of HAADF-STEM. A relationship between K-induced 1T′ and 2H-MoS₂ phases and the catalytic property to synthesize CH₃SH was established, and K-intercalated 1T′-MoS₂ phase was confirmed to have excellent catalytic performances. Moreover, the behavior, origin, and influencing factors of phase transformation of 2H-MoS₂ from/to 1T′-MoS₂ in the existence of K were well proved.
High-throughput optimization of near-infrared-transparent Mo-doped In<inf>2</inf>O<inf>3</inf> thin films with high conductivity by combined use of atmospheric-pressure mist chemical-vapor deposition and sputtering

Approximately 85% of Mo in the IMO film deposited at Td = 500 °C was in the + 4 oxidation state (BE ≈ 231.5 eV). Mo4 + peak from oxides generally appears at binding energies ranging from 231.0 to 232.0 eV [54–57]. According to the Mo–O phase diagram [64], the + 4 oxidation state is more stable than the + 6 state at high temperature.
Thin films of near-infrared (NIR)-transparent and highly conductive Mo-doped In₂O₃ (IMO) were prepared as transparent electrodes in thin-film photovoltaic cells and energy-efficient windows. The fabrication process was rapidly optimized by the combined use of atmospheric-pressure mist chemical-vapor deposition (mist-CVD) and sputtering. Mist-CVD was used to rapidly deposit IMO thin films with various Mo-dopant concentrations. We obtained highly conductive IMO thin films with transmittance above 70% in a wide wavelength range of 0.3–2.5 μm when the Mo-dopant concentration was ~ 1 at% and the Mo dopants had an oxidation state of + 4. The IMO films with the optimum Mo-dopant concentration of ~ 1 at% had low resistivities of (3–4) × 10^− 4 Ω cm resulting from high electron mobilities exceeding 80 cm² V^− 1 s^− 1and suppressed electron densities of (2–3) × 10^− 4 cm^− 3, which prevented the degradation of transparency in the NIR region. We applied these findings to the growth of IMO thin films by sputter deposition, which is readily extendable from laboratory scale to industrial scale. As a result, a high-performance IMO film was successfully obtained in only a few deposition runs. The optimized sputtered IMO film exhibited an extraordinarily high electron mobility of 93 cm² V^− 1 s^− 1 and relatively low electron density of 1.5 × 10²⁰ cm^− 3, leading to a plasma wavelength that was longer than 4 μm. This optimized IMO film allowed passage of the full solar spectrum and exclusively reflected far-infrared light corresponding to thermal radiation at room temperature, allowing it to be used as transparent electrodes in photovoltaic cells and heat-reflective electrodes in energy-efficient electrochromic windows. We believe the combination of mist-CVD and sputtering can be extended to rapid optimization of other functional oxide systems.
Effect of radio frequency power on composition, structure and optical properties of MoSe<inf>x</inf> thin films
2014, Physica B: Condensed Matter

The BEs of Mo 3d5/2 for Mo–Se, Mo–Mo and Mo–O as a function of RF power are shown in Table 2. The BEs of Mo 3d5/2 for Mo–Se, Mo–Mo and Mo–O were reported to be 228.7±0.2 eV [14,25], 228.2±0.2 eV [26,27], and 230.2 eV [28,29], respectively. It can be seen from Table 2 that the BEs of Mo 3d5/2 are in agreement with the reported ones.
MoSe_x films were prepared by radio frequency (RF) magnetron sputtering under various RF powers in the range of 40–130 W. Effects of RF power on composition, structure and optical properties of MoSe_x films were investigated. Results show that the chemical bonding, binding energy, structure, and optical properties of MoSe_x films depend greatly on RF power. When the RF power varies from 40 to 70 W, the bonding atomic ratio of Se/Mo in MoSe_x films increase and Mo 3d_5/2 and Se 3d_5/2 peaks shift towards lower binding energies. With further increase in the RF power from 70 to 130 W, the bonding atomic ratio of Se/Mo in MoSe_x films decreases and Mo 3d_5/2 and Se 3d_5/2 peaks move to higher binding energies. Structures of MoSe_x films are amorphous with the RF power ≤70 W, whereas structures of MoSe_x films exhibit nanostructure with the RF power >70 W. Moreover, MoSe_x films deposited at 70 W have larger refractive index, lower extinction coefficient, and higher band gap than those deposited at other RF power.
Surface modification of the MoSiON phase shift mask to reduce critical dimension variation
2013, Applied Surface Science
Citation Excerpt :
As for Mo3d, the as-received and NH3-annealed PSM layers had identical XPS spectra, as shown in Fig. 6(d). We attributed the deconvoluted peaks at 230.0 and 233.0 eV to Mo4+ and Mo6+, respectively [17,18], which were barely detectable on the surface of the PSM layer after plasma treatment. Details of the XPS depth profiles are provided in the Supplement.
Phase shift masks (PSMs) were introduced to extend the limits of optical lithography. However, cleaning a MoSiON-based PSM pattern with an ammonium hydroxide/hydrogen peroxide mixture (APM), although efficient at cleaning the PSM pattern, etches the PSM layer, inducing changes in the phase angle and transmittance due to the introduction of variation of the critical dimension (CD). In this study, we investigated the effects of plasma treatment and furnace annealing on the etching of the MoSiON PSM in APM. In particular, we found that the etch behavior and surface chemical state after each treatment were correlated. We also compared variations in the CD between patterned PSM layers and blank masks. After O₂ or N₂ plasma treatment, the top surface of MoSiON had a thicker transition layer with an extreme increase in O, and a huge variation in CD was also observed after APM treatment. However, CD variation of the patterned MoSiON layer was minimal when the sample was first annealed in NH₃ ambient gas and then subjected to APM treatment. This phenomenon may be related to an increase in the portion of the SiO₂-like state at the top surface of the MoSiON PSM layer and its optimization without a change in the transition layer thickness.
Ultrasonic-assisted synthesis of highly dispersed MoO<inf>3</inf> nanospheres using 3-mercaptopropyltrimethoxysilane
2008, Ultrasonics Sonochemistry
With ultrasonic irradiation as assistance, highly dispersed MoO₃ nanospheres were synthesized using silane coupling agent 3-mercaptopropyltrimethoxysilane HS-(CH₂)₃Si(OCH₃)₃ (MPTS) as figuration agent. The results of X-ray powder diffractometer (XRD) showed that the precursor was hexagonal molybdenum oxide hydrate (MoO₃ 0.55H₂O). It was converted into orthorhombic MoO₃ after annealed at 400 °C for 2 h. Transmission electron microscopy (TEM) showed that MoO₃ · 0.55H₂O and MoO₃ nanoparticles were spherical with particle-size distribution of ca. 30–80 nm and 25–75 nm, respectively. Results indicated that MPTS and ultrasonic irradiation played important role in formation of highly dispersed MoO₃ nanospheres. X-ray photoelectron spectroscopy (XPS) was also adopted to confirm the growth mechanism. The possible cause of formation was based on dispersion function of ultrasonic irradiation and figuration of MPTS.
Intercalation of MoCl<inf>5</inf> into graphite-determining factor to control stage structure
1999, Synthetic Metals
The mechanism of formation of MoCl₅–graphite intercalation compounds (MoCl₅–GICs) was proposed on the basis of the experimental results obtained in the present and previous works. The amount of reactive chlorine formed in the reaction system was concluded to be the determining factor for the stage structure in resulting MoCl₅–GICs. Reactive atomic chlorine produced during the decomposition of only 2% MoCl₆, which was formed from MoCl₅ at high temperature, seemed not enough for the formation of pure stage 1 MoCl₅–GIC and therefore only stage 2 structure was obtained. Heating the MoCl₅ in presence of either MoOCl₃ or MoO₃ formed MoOCl₄, which evolved high amount of reactive chlorine which formed the stage 1 MoCl₅–GIC in single phase.
