“…Wang and coworkers demonstrated a Pt metal induced nucleation to successfully realize the CVD growth of ReS 2 flowers at controlled locations (Figure 7b). [ 124 ] To achieve the large‐scale fabrication, a highly controllable and precise atomic layer deposition (ALD) technique, another bottom‐up synthesis approach, is applied to deposit 3D ReS 2 nanoarrays. [ 125 ] By controlling the growth temperature (from 120 to 500 °C), 3D ReS 2 nanosheets with vertical orientation and petal‐like morphology (Figure 7c) were obtained on large‐area (5 cm × 5 cm) Al 2 O 3 coated Si (110) substrate using easily sublimated ReCl 5 and H 2 S as precursors.…”

The rise of 2D transition-metal dichalcogenides (TMDs) materials has enormous implications for the scientific community and beyond. Among TMDs, ReX 2 (X = S, Se) has attracted significant interest regarding its unusual 1T′ structure and extraordinary properties in various fields during the past 7 years. For instance, ReX 2 possesses large bandgaps (ReSe 2 : 1.3 eV, ReS 2 : 1.6 eV), distinctive interlayer decoupling, and strong anisotropic properties, which endow more degree of freedom for constructing novel optoelectronic, logic circuit, and sensor devices. Moreover, facile ion intercalation, abundant active sites, together with stable 1T′ structure enable them great perspective to fabricate high-performance catalysts and advanced energy storage devices. In this review, the structural features, fundamental physicochemical properties, as well as all existing applications of Re-based TMDs materials are comprehensively introduced. Especially, the emerging synthesis strategies are critically analyzed and pay particular attention is paid to its growth mechanism with probing the assembly process of domain architectures. Finally, current challenges and future opportunities regarding the controlled preparation methods, property, and application exploration of Re-based TMDs are discussed.

“…The crystallographic structure of CVD‐grown ReS 2 was further characterized by transition electronic microscopy (TEM) and selected area electron diffraction (SAED). The ReS 2 flakes were transferred onto TEM grid using the same transfer method as reported previously . Figure a shows a typical TEM image of the ReS 2 sample, in which the ReS 2 single crystal has not been damaged during the transfer process.…”

It is important to recognize the axial direction of ReS 2 single crystals, with considerable anisotropy in electrical and optical properties, which are expected to have a wide application in photoelectric devices. Here, we successfully synthesize ReS 2 single crystals with triangle and parallelogram shapes on SiO 2 substrate by a chemical vapor deposition (CVD) method and propose a simple approach to recognize the axial direction of ReS 2 single crystals just by comparing the ratio of the edge lengths, which are confirmed by transmission electron microscopy images. In addition, the mobility of a prepared ReS 2 field effect transistor is 8.16 cm 2 V À1 s À1 and the on/off ratio is up to 10 5 .

“…For example, a high deposition rate was achieved to deposit n-type coating on sapphire substrate under a low pressure [2]. Another feature of CVD is that the structures of deposited materials may be enhanced by pre-patterned metal dot catalysts [3,4]. CVD has been used for depositing various thermoelectric materials including silicon nanowires [5,6], SiC [7,8], oxides [9], Ge nanocones [10], and Se-C films [11].…”

Complex materials have unique thermal and electron transport properties. In this work, a novel catalyst-assisted metal organic chemical vapor deposition approach was employed to make BiTe -Ni-Cu-Au complex materials on an anodic aluminum oxide nanoporous substrate. Nickel acetate, copper nitrate, bismuth acetate, and tellurium (IV) chloride dissolved in N,N-dimethylformamide (DMF) were used as the metal sources for Ni, Bi, Cu, and Te, respectively. Hydrogen was used as the carrier gas. The anodic aluminum oxide substrate sputter-coated on a thin gold coating and was kept at 500 • C in a quartz tube in the reaction chamber. The chemical vapor deposition time was two hours. Scanning electron microscopy was used to reveal the morphology of the deposited materials. Due to metal catalyst assisted growth, the BiTe -Ni-Cu-Au materials were self-assembled into islands distributed fairly uniformly on the substrate. The mechanism for the morphological development of the materials was investigated. It was found that the Au nanoparticles facilitated the formation of the complex BiTe -Al-Ni-Cu materials. The prepared nanostructure has the highest absolute Seekbeck coefficient value of 260 µV/K, which is more than twice the value obtained from the bulk material.
