English: Nanostructured gallium arsenide was synthesized by a two-stage anodic etching method followed by electrochemical deposition. This ensures that the crystal has several structural phases and consists of different compounds. The flower-like crystallite is an oxide. Thin "petals" of the crystallite around one center indicate that the structure was formed from a single nucleation center likely being the dislocation outcrop to the crystal surface. Native metal oxides of gallium arsenide have recently become the research target by many scientific groups around the world thanks to the prospects for their use in modern electronic and photonic devices. The nanostructure was synthesized in the nanostructures synthesis laboratory of the Berdiansk State Pedagogical University. The micrograph was obtained using a SEO-SEM Inspect S50-B scanning microscope (Sumy State University). 5000x magnification. Image width: 50 µm. The image was colorized using Adobe Photoshop without any further manipulations with the image. The work was created within the framework of the Grant of the President of Ukraine for the implementation of Serhii Kovachov's "Nanoart Artbook" creative project. Creators of the work: Yana Sychikova (nanostructures synthesis) and Serhii Kovachov (color design).
