Special Issue Information

Dear Colleagues,

Nanoscale sized materials and particularly, metallic, magnetic and semiconducting nanowires, are nowadays attracting a great deal of attention among scientists coming from different research fields, due to their peculiar physico-chemical features, exhibited due to their nanometer size dimensions and specific geometries. Therefore, wire-shaped nanomaterials have become key elements in many modern technological approaches, including magnetic data storage, energy conversion and harvesting, catalysis, sensing, photonics and many others.

This Special Issue is aimed at providing selected contributions on advances in the synthesis, characterization and prospective technological applications of nanowires, featuring recent and novel developments in chemistry, physics, materials science and engineering, biology or medicine, among many other disciplines. Gaining a thorough understanding regarding different synthesis conditions of nanowires and the characterization of their properties by employing several experimental techniques, will help us to move forward in real-world technical applications.

The scope of this Special Issue covers broad and interdisciplinary research areas where the one-dimensionality of nanowires becomes noteworthy. Topics and applications in which nanowires are being currently used, can include, but are not limited to, magnetic sensors and data storage in race track memory devices, photovoltaic cells, fuel cells, thermo-electric devices, batteries, super-capacitors, photocatalyst, electronic devices and spintronics, etc.

The impact of mixed defects on ZnO phononic and photonic properties at the nanoscale is only now being investigated. Here we report an effective strategy to study the distribution of defects along the growth direction of a single ZnO nanowire (NW), performed qualitatively as well as quantitatively using energy dispersive spectroscopy (EDS), confocal Raman-, and photoluminescence (PL)-mapping technique. A non-concomitant near-infrared (NIR) emission of 1.53 ± 0.01 eV was observed near the bottom region of 2.05 ± 0.05 μm along a single ZnO NW and could be successfully explained by the radiative recombination of shallowly trapped electrons V_O^(**) with deeply trapped holes at V_Zn^''. A linear chain model modified from a phonon confinement model was used to describe the growth of short-range correlations between the mean distance of defects and its evolution with spatial position along the axial growth direction by fitting the E2H mode. Our results are expected to provide new insights into improving the study of the photonic and photonic properties of a single nanowire. Full article
