Special Issue Information
Dear Colleagues,
Nano-optoelectronics and nano-photonics are revolutionary disciplines that delve into the fascinating world of light–matter interactions at the nanoscale. At this minuscule level, typically on the order of nanometers, materials exhibit extraordinary optical and electronic properties that diverge from those observed in macroscopic systems. These fields combine nanotechnology, optics, and electronics to create innovative devices with exceptional capabilities. In nano-optoelectronics, the focus lies in seamlessly integrating optics and electronics at the nanoscale. This entails developing nanoscale light-emitting diodes, photodetectors, and other optoelectronic components to enable faster and more energy-efficient computing, data communication, and imaging technologies. Nano-photonics, on the other hand, concentrates on controlling and manipulating light itself at the nanoscale. Researchers explore phenomena like plasmonics, metamaterials, and photonic crystals to engineer devices that can tailor light propagation, absorption, and emission. These advancements have promising applications in ultra-compact photonic circuits, high-speed communication, and quantum information processing. The synergy between nano-optoelectronics and nano-photonics promises to transform various industries, leading to the development of cutting-edge technologies that will shape the future of science and engineering.
This Special Issue aims to present original state-of-the-art research articles on carbon-based nano-optoelectronics and nano-photonics and their applications. Researchers are invited to submit their contributions to this Special Issue. Topics include, but are not limited to, the following:

Title: Novel Self-Powered Gas Sensors Based on PENGs with Cr-Doped ZnO Nanorods
Authors: Kai-Lin Yang; Liang-Wen Ji
Affiliation: Institute of Electro-Optical and Materials Science, National Formosa University, Yunlin 632, Taiwan.
Abstract: In this investigation, chromium-doped ZnO nanorod (NR) arrays were grown on ITO/PET substrates using a hydrothermal method. Subsequently, self-powered gas sensors based on piezoelectric nanogenerators (PENGs) were fabricated and characterized. The chromium doping concentration in the ZnO NRs was estimated to be 0.4 wt% using energy-dispersive X-ray spectroscopy (EDS). Additionally, transmission electron microscope (TEM) results revealed that the as-grown ZnO NRs exhibited a hexagonal wurtzite structure. During the device fabrication process, the top electrode patterns were defined through laser engraving, and silver thin films were deposited on the ITO-PET substrates using the RF-sputtering technique. The PENGs were composed of the silver top electrodes and the bottom of chromium-doped ZnO NRs. A specialized impacting system has been employed to drive the fabricated PENGs with a fixed frequency. Under the doping condition of 0.5 mM chromium nitrate, it can be found that the output voltages of the PENG were measured to be 1.447 V and 2.323 V respectively, without and with introducing 100 ppm of nitric oxide (NO). Clearly, such a device exhibits an excellent self-powered characteristic and demonstrates good sensitivity to NO gas.
