Summary: In this study, a zinc sulfide (ZnS) nanostructure film was successfully deposited on multi-walled carbon nanotubes (MWCNTs) using pulsed laser deposition technique. The ZnS/MWCNTs nanocomposite prepared at 5.3 J/cm² exhibited the best crystallinity. Scanning electron microscope (SEM) analysis revealed that the deposited ZnS films had a smooth structure with spherical particles attached to the surface. The current-voltage characteristics of the ZnS-decorated MWCNTs/Si heterojunction photodetectors showed high responsivity values, indicating the potential of these devices for optical sensing applications.

Summary: In this study, ZnO aerogels with different concentrations of Al or Na dopants were successfully synthesized using a sol-gel process. The Al-doped aerogels showed a significant decrease in bandgap and an increase in specific surface area. By depositing the doped ZnO aerogels on ITO-coated glass substrates using a drop casting method, p-n homojunctions with characteristic diode rectifying behavior were obtained.

Summary: ZnO is a significant semiconductor material widely used in various fields due to its direct band gap, large exciton binding energy, and easy growth of high-quality nanostructures. However, obtaining high-quality p-type ZnO has been a major challenge. In this review, we discuss various methods such as increasing acceptor concentration, shallowing acceptor energy levels, and reducing donor defects to obtain high-quality p-ZnO. We also summarize the applications of p-ZnO in LEDs, UV detectors, thin-film transistors, gas sensing, and bionic materials.

Summary: In this study, a copper oxide thin film was prepared using the CW laser assisted-chemical bath deposition (LACBD) technique. The effect of laser wavelength on the structural, optical, and electrical properties of CuO film was investigated. Increasing the laser wavelength resulted in decreasing the grain size of the film and enhancing the crystallization. The p-CuO/n-Si heterojunction photodetectors exhibited two peaks of response at 450 nm and 800 nm.

Summary: This study investigates the deposition of nanostructures by room temperature pulsed laser deposition (PLD) in low pressure gases (O-2, N-2, He, and Ar) at different substrate positions. The results show that different gases have different effects on optical emission and ion velocity. It is suggested that collisions of the ablated specie result in strong emission and impede the ion velocity. Amorphous films are obtained in all gases at the on-axis/center position and in O-2 at the bottom position. Crystalline ZnO and Zn nanostructures are deposited at the bottom position in N-2, He, and Ar. The presence of nanorods is detected in Ar. Zn crystallites are also detected, which can act as catalyst for nanostructure formation.

Summary: An ultrasensitive phototransistor based on a laser-induced p-doped WSe2/MoS2 van der Waals heterojunction is reported. Compared to the pristine WSe2/MoS2 heterojunction, the p-doped WSe2/MoS2 exhibits a stronger built-in electric field, leading to improved separation of photogenerated electron-hole pairs and enhanced electron injection into MoS2. As a result, high photoresponsivity and detectivity are achieved, which are approximately two orders higher than the best WSe2/MoS2 phototransistor.

Summary: Due to the small valence band discontinuity at NiO/Si interface, the p-NiO/n-Si heterojunction photodiodes have poor UV detection. However, by sandwiching a ZnO layer between p-NiO and n-Si, the UV response is largely enhanced due to the large valence band discontinuity at ZnO/Si interface. The ZnO layer also suppresses the dark current and increases the detectivity of the photodiodes.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
