Synthesis of quasi-one-dimensional nanomaterials and heterostructures based on zinc and copper oxides

ZnO nanostructures are used in optical electronics and microelectronics, microsystems engineering. Characteristics of ZnO-based materials are improved by producing heterojunctions with oxides of other metals, including copper oxide. The use of quasi-one-dimensional structures provides the possibility for the total surface area of a heterojunction to be increased. Investigations aimed at the study of controlling the morphology of quasi-one-dimensional oxides are rather limited, so that the aspect considered in this regard continues to be very relevant. As a result, the search for the most efficient synthesis processes that give not only greater productivity, but also higher quality and improved material properties continues. A method for the synthesis of the ZnO/CuO heterostructure based on zinc oxide nanowires by pulse-periodic laser irradiation is described. The improvement of systems for shaping the laser beam with elements of diffractive computer optics provides an opportunity to control the processes involved in such synthesis.
