“…This is mainly because the interfacial orientation of ZnO changes the original growth direction of MoS 2 . Similar phenomena were also observed in the study of Liu et al [27] The cross section of the Janus-type membrane is shown in Figure 1f. The thicknesses of ZnO and MoS 2 films are 97 and 296 nm, respectively.…”

Novel multifunctional Janus‐type membrane with both hydrophobic and anticorrosion abilities is constructed on the surface of aluminum (Al), using MoS2 as a hydrophobic layer and ZnO as a corrosion‐resistant layer. Al anode coated with the Janus‐type membrane is used as an example to study the specific property of the as‐prepared Janus‐type membrane. In the Al–air battery, the self‐corrosion of the Al anode is well inhibited since the Janus‐type membrane can block the invasion of excess hydroxide ions and water molecules simultaneously. The results show that the inhibition efficiency of the Janus‐type membrane is as high as 79.2%. Furthermore, the electrochemical measurements demonstrate that the discharge specific capacity of the Al–air battery with the Janus‐type membrane can reach up to 2095 mAh g−1, approximately two times as much as that of traditional batteries. The integrated strategy of combining hydrophobic and anticorrosion membrane is a novel method for corrosion protection of metal electrode. This Janus‐type membrane holds a great potential toward corrosion inhibition for the other metal in alkaline environment as well.

“…The growth mode of MoS 2 with I-type (c ∥ ) and II-type (c ⊥ ) on MoTe 2 corresponds to the c -axis parallel and perpendicular to the substrate plane, respectively. In refs and , the growth mode of MoS 2 by the magnetron sputtering method has been reported and is summarized in Figure S2. With the change of sputtering temperature and time, the final growth mode of MoS 2 is I-type stacked II-type.…”

Semiconducting 2D layered transition metal dichalcogenides (TMDs) and TMD heterostructures have attracted much attention in porous materials because of their unique electrical and optical properties. However, the role of controlled epitaxial growth and strain in the interfacial electron transfer and nonlinear optical (NLO) conversion efficiency of the TMD/ TMD nanoheterostructure remains poorly understood. Herein, we have successfully synthesized a MoS 2 /MoTe 2 nanoheterostructure with excellent photoelectric and NLO properties. The designed MoS 2 /MoTe 2 nanoheterostructure exhibits excellent NLO performance, including a high nonlinear absorption (NLA) coefficient of 10 −7 cm/W at the pulse energy of 5 μJ, which is attributed to the enhanced light absorption capacity of MoTe 2 and the modulation of interlayer carrier diffusion. Based on the synergistic effects of optimization strain and interface engineering, an in-depth analysis was conducted on the effects of surface modification on the photoelectrochemical (PEC) performance optimization of the MoS 2 /MoTe 2 nanoheterostructure. The synergistic effect of strain and the interface can promote the continuous transfer of electrons between MoTe 2 and MoS 2 . This work studied the visualization control interface and interlayer electron/exciton phonon coupling in van der Waals MoS 2 /MoTe 2 , providing some inspiration for achieving good NLO conversion efficiency and efficient PEC anode materials.

“…In order to better understand ZnO’s optical processes under laser excitation, it is necessary to characterize its NLA behavior. Some studies have been conducted on the nonlinear properties of ZnO in a narrow wavelength range or using a megahertz repetition-rate laser. − At present, the dynamic behaviors of ZnO semiconductor materials in different wavebands and pulse time domains have also been reported. − …”

Morphology-rich ZnO as a direct band gap II−VI semiconductor is a promising material for photonic, optical, and electronic devices. Nanostructured materials have provided a leading edge to the next-generation technology due to their distinguished performances and efficiencies for device fabrication. The nonlinear optical (NLO) properties and mechanisms dependent on the size and dimensionality of ZnO nanostructures remain to be elucidated. Herein, we begin to provide a comprehensive summary of the status of research activities in ZnO nanostructures, including their syntheses and potential applications, with an emphasis on multidimensional ZnO nanostructure based growth, properties, and applications. Density functional theory calculations confirmed the effect of ZnO size, morphology, and defect on the structure, work function, and charge density distribution of the electron band. Finite difference time domain simulation confirmed that the electric field, magnetic field, and Poynting vector of the ZnO system with the morphology changes were applied. Moreover, the ultrafast NLO and carrier dynamics of feature-rich ZnO nanostructures were studied. The effects of different experimental parameters on the morphology and linear and nonlinear excitation and radiation mechanisms of ZnO nanostructures were studied by constructing an electron transfer mechanism diagram and the Z-scan technique. The results show that the properties and properties of ZnO nanostructures can be regulated and controlled by the structure and morphology. The application and performance of feature-rich zinc oxide nanostructures in photoelectric functional devices are prospected, which will provide valuable references and guidance for related researchers.
