“…Over the years, the resistive heating thermal evaporation technique has been the most commonly used method to deposit ZnTe thin films, which is a simple, low cost, reproducible and excellent technique with optimum control over the deposition rate, substrate temperature, and film thickness. 84,[99][100][101][102][103][104] Numerous researchers have employed this technique to fabricate ZnTe thin films and solar cell devices. [105][106][107][108][109] In the thermal evaporation technique, the source material is kept in a filament (boat of molybdenum, tungsten, and tantalum or tungsten basket), where the source material is heated to its melting point using electrical energy under high vacuum.…”

“…All these peaks strongly suggest that negative functional groups are present on the surface of the synthesized Ti 3 C 2 T x nanosheets. The absorption band appearing around 745 cm –1 for pristine MoTe 2 corresponds to the metal-telluride vibrations. − Peaks appearing at 890 cm –1 are assigned to the metal oxide bond . The peak at 1401 cm –1 is generated from the coupling of the bending vibration of O–H .…”

Hydrogen as an energy source has been regarded as a clean and efficient energy carrier and as a promising alternative to traditional fossil fuels. Among numerous hydrogen generation systems, water splitting is deemed as the most productive technology to generate clean and high-purity hydrogen. The prominent features-based two-dimensional (2D) materials have proven themselves as efficient as well as robust electrocatalysts for the hydrogen evolution reaction (HER). Here we designed a remarkably active and durable HER catalyst by integrating semimetallic 1T′ MoTe2 petal clusters on Ti3C2T x nanosheets by a facile hydrothermal approach. As-prepared MoTe2/Ti3C2T x hybrids exhibited significantly enhanced electrocatalytic HER performance, generating a cathode current density of 10 mA/cm2 at an overpotential of only 293 mV with a small Tafel slope of 65 mV/dec and satisfactory long-term stability in acidic media. The experimental results are further verified by the first-principles studies presenting the geometrical and electronic properties of MoTe2, Ti3C2T x , and MoTe2/Ti3C2T x hybrids. The interaction between the Ti3C2T x and MoTe2 is due to charge transfer from Ti3C2T x to MoTe2. Theoretically, we have calculated the overpotential for HER activities. Computed overpotential follows the qualitative trend of MoTe2/Ti3C2T x < MoTe2 < Ti3C2T x , which supports the experimental findings. The unique aspects of these unique hybrids, such as semimetallic nature MoTe2 petal clusters and strong interface interaction between MoTe2 and conductive Ti3C2T x nanosheets, cause superior HER catalytic performance. We believe these outcomes accentuate the promising perspective of MoTe2/Ti3C2T x hybrids as a capable and nonprecious catalyst and provide an auspicious prospect for the development of 2D materials-based HER electrocatalysts.

“…Different techniques can be employed for the deposition of MNPs, including electroless deposition via a chemical solution [ 9 , 12 , 13 ], pulsed laser ablation [ 11 ], drop-casting [ 16 ], thermal evaporation [ 5 , 18 ], and more. The later technique is recommended and is one of the simplest and economical methods, enabling easy material anchoring with good properties and reduced surface damage [ 19 , 20 , 21 ].…”

A key requirement for the development of highly efficient silicon nanowires (SiNWs) for use in various kinds of cutting-edge applications is the outstanding passivation of their surfaces. In this vein, we report on a superior passivation of a SiNWs surface by bismuth nano-coating (BiNC) for the first time. A metal-assisted chemical etching technique was used to produce the SiNW arrays, while the BiNCs were anchored on the NWs through thermal evaporation. The systematic studies by Scanning Electron Microscopy (SEM), energy dispersive X-ray spectra (EDX), and Fourier Transform Infra-Red (FTIR) spectroscopies highlight the successful decoration of SiNWs by BiNC. The photoluminescence (PL) emission properties of the samples were studied in the visible and near-infrared (NIR) spectral range. Interestingly, nine-fold visible PL enhancement and NIR broadband emission were recorded for the Bi-modified SiNWs. To our best knowledge, this is the first observation of NIR luminescence from Bi-coated SiNWs (Bi@SiNWs), and thus sheds light on a new family of Bi-doped materials operating in the NIR and covering the important telecommunication wavelengths. Excellent anti-reflectance abilities of ~10% and 8% are observed for pure SiNWs and Bi@SiNWs, respectively, as compared to the Si wafer (50–90%). A large decrease in the recombination activities is also obtained from Bi@SiNWs heterostructures. The reasons behind the superior improvement of the Bi@SiNWs performance are discussed in detail. The findings demonstrate the effectiveness of Bi as a novel surface passivation coating, where Bi@SiNWs heterostructures are very promising and multifunctional for photovoltaics, optoelectronics, and telecommunications.
