Article Abstract
Highly-symmetrical well-crystallized comb-like ZnO nanostructures were grown in a very large-quantity on the aluminum foil via non-catalytic thermal evaporation method by using metallic zinc powder in the presence of oxygen at low temperature of 440 degrees C. Detailed morphological investigations revealed that the as-grown combs are made with a ribbon-like stem and aligned nanorod/nanowire arrays attached uniformly and nicely along one side of the ribbon-like stem. The X-ray diffraction (XRD) pattern and high-resolution transmission electron microscopy (HRTEM) revealed that the as-grown nanocombs are crystalline and possessing a wurtzite hexagonal phase. The optical properties were observed by room-temperature photoluminescence (PL) and Raman-scattering which exhibited good optical properties for the as-grown products. A plausible growth mechanism has also been proposed for the formation of highly symmetrical comb-like ZnO nanostructures.

One-dimensional (1D) Zn-based heterostructures have attracted considerable interest in the field of photodetection because of their tunable properties, flexibility, and unique optoelectronic properties. However, designing 1D multi-component Zn-based heterostructures for advanced photodetectors is still a great challenge. Herein, comb-like 1D-1D ZnO-ZnSe heterostructures with ZnO and ZnSe nanowires (NWs) comprising the shaft and teeth of a comb are reported.

The wide direct bandgap and strong exciton binding energy of ZnO have inspired examinations of ultraviolet lasing over the previous decades. However, regulation of the lasing mode, especially the realization of single mode lasing, is still a challenge. In this study, a ZnO comb-like structure with an array of microrods was selected to design coupled whispering-gallery-mode cavities, wherein the naturally varied air-gap between the adjacent microrods created a flexible condition for optical field coupling without any complicated micromanipulation.

Self-assembly of two-dimensional (2D) nanosheets and one-dimensional (1D) nanorods into three-dimensional (3D) double-sided comb-like ZnO nanostructures has been successfully performed via a simple one-step hydrothermal method on Si and ITO substrates. It is found that the thickness of the ZnO seeds plays a vital role in the formation of 3D double-sided comb-like ZnO.

On-chip integrations of photonic waveguides and high-performance electrically-driven devices, by combining different active or passive optical components, are imperative towards the advancement of nanophotonic circuitry systems. We experimentally demonstrate the collective optical functionalities of ZnO microstructures towards designing an integrated photonic system by combining the optical waveguiding and detection properties. Comb-like microstructures composed of periodic arrays of smooth, single-crystalline ZnO nanowires are synthesized for these purposes.

Increasing the temperature variation rate is a useful method for enhancing the response of pyroelectric devices. A three-dimensional ZnO film was fabricated by the aerosol deposition (AD) rapid process using the shadow mask method, which induces lateral temperature gradients on the sidewalls of the responsive element, thereby increasing the temperature variation rate. To enhance the quality of the film and reduce the concentration of defects, the film was further treated by laser annealing, and the integration of a comb-like top electrode enhanced the voltage response and reduced the response time of the resulting ZnO pyroelectric devices.
