Creation of One- and Two-Dimensional Copper and Zinc Oxides Semiconductor Structures

Abstract

The most effective methods for the synthesis of nanostructured copper and zinc oxides, which have unique properties and potential applications in a variety of fields including electronics, photonics, sensorics, and energy conversion, are analyzed. Special attention is paid to laser-based methods for synthesizing oxide nanostructures, with an emphasis on the importance of controlling power density distribution to influence the quality and properties of the nanomaterials. The great significance of wavefront shaping techniques for controlling laser-initiated processes is highlighted, which enable precise control over the phase and amplitude of light waves to achieve desired outcomes in optics and laser-assisted formation of one- and two-dimensional structures of oxide semiconductor materials. Diffractive computer optics is presented as a powerful tool for precise beam control. The significance of laser-induced thermochemical processes for creating and improving the properties of ZnO and CuO-based nanomaterials is discussed. The presented analysis shows that the synthesis of nanocomposites based on ZnO and CuO using pulse-periodic laser treatment, coupled with precise laser beam control using free-form diffractive optics, presents novel opportunities for applications in optoelectronics, sensor technology, electronics and portable energy sources manufacturing, and various other fields.

Fabrication of Smart Materials Using Laser Processing: Analysis and Prospects

“…An encouraging application of computer-generated DOEs involves the precise fabrication of nanostructures in the form of porous and oxide-metallic materials. Manipulating nanostructure morphology within specific regions of the laser-affected zone can be effectively addressed by modifying the laser beam's shape and redistributing its energy, particularly power density [206][207][208]. For the processing tasks, a CO 2 laser with diffusion cooling and radio frequency excitation was utilized.…”
