Aero-Ga2o3 nanomaterial electromagnetically transparent from microwaves to terahertz for internet of things applications. Nanomaterials. 2020, vol. 10, pp. 1-10. ISSN 2079-4991.2079-4991https://msuir.usm.md/handle/123456789/16220https://doi.org/10.3390/nano10061047In this paper, fabrication of a new material is reported, the so-called Aero-Ga2O3 or Aerogallox, which represents an ultra-porous and ultra-lightweight three-dimensional architecture made from interconnected microtubes of gallium oxide with nanometer thin walls. The material is fabricated using epitaxial growth of an ultrathin layer of gallium nitride on zinc oxide microtetrapods fabricated using epitaxial growth of an ultrathin layer of gallium nitride on zinc oxide microtetrapods followed by decomposition of sacrificial ZnO and oxidation of GaN which according to the results of X-ray diffraction (XRD) and X-ray photoemission spectroscopy (XPS) characterizations, is transformed gradually in β-Ga2O3 with almost stoichiometric composition. The investigations show that the developed ultra-porous Aerogallox exhibits extremely low reflectivity and high transmissivity in an ultrabroadband electromagnetic spectrum ranging from X-band (8–12 GHz) to several terahertz which opens possibilities for quite new applications of gallium oxide, previously not anticipated.enaero-Ga2O3ultra-porous nanomaterialextremely low reflectivityelectromagnetically transparent nanomaterialX-band and terahertz frequenciesArticle
