In the process of laser treatment in air using the synergy of heat exposure and vibrations induced by laser with a force fundamental frequency of 100 Hz, the brass surface of samples is oxidized mainly with the generation of ZnO nanowires. The condition for intensification is the local non-stationary deformation caused by sound waves induced by laser. Upon the initiation of the processes of exfoliation of the initially formed layers on the material surface, apart from a disordered structure, a structure was formed in the central region containing two-dimensional objects made of zinc oxide with characteristic thicknesses of 70\u2013100 nm. Such arrays can provide the potential to create a periodic localized electric field applying direct current, this allows the production of electrically switched diffraction gratings with a variable nature of zones. It has been established that during laser pulse-periodic irradiation on brass, the component of the metal alloy, namely, zinc, will oxidize on the surface in the extent that its diffusion to the surface will be ensured. During laser pulse-periodic heating under conditions of the experiment, the diffusion coefficient was 2\u20133 times higher than from direct heating and exposure to a temperature of 700 \u00b0C. The study of the electrical resistance of the created samples by the contact probe method was performed by the four-point probe method. It was determined that the specific electrical resistance at the center of the sample was 30\u201340% more than at the periphery. To determine the possibility of using the obtained material based on zinc oxide for the creation of sensors, oxygen was adsorbed on the sample in an oxygen\u2013argon mixture, and then the electrical resistance in the central part was measured. It was found that the adsorbed oxygen increases the electrical resistivity of the sample by 70%. The formation of an oxide layer directly from the metal substrate can solve problem of forming an electrical contact between the gas-sensitive oxide layer and this substrate.<\/jats:p>","DOI":"10.3390\/s20195575","type":"journal-article","created":{"date-parts":[[2020,9,29]],"date-time":"2020-09-29T08:43:27Z","timestamp":1601369007000},"page":"5575","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Arrays Formation of Zinc Oxide Nano-Objects with Varying Morphology for Sensor Applications"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8150-1848","authenticated-orcid":false,"given":"Serguei P.","family":"Murzin","sequence":"first","affiliation":[{"name":"Samara National Research University, Moskovskoe Shosse 34, 443086 Samara, Russia"},{"name":"Institute of Production Engineering and Photonic Technologies, TU Wien, Getreidemarkt 9, 1060 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolay L.","family":"Kazanskiy","sequence":"additional","affiliation":[{"name":"Samara National Research University, Moskovskoe Shosse 34, 443086 Samara, Russia"},{"name":"Image Processing Systems Institute of RAS\u2014Branch of the Federal Scientific Research Centre Crystallography and Photonics of Russian Academy of Sciences, Molodogvardejskaya street 151, 443001 Samara, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"156","DOI":"10.1364\/AOP.8.000156","article-title":"Diffraction gratings: From principles to applications in high-intensity lasers","volume":"8","author":"Bonod","year":"2016","journal-title":"Adv.
