Abstract
Anisotropic CuCrO2 thin films were successfully prepared on glass substrate by the electrospinning method followed by annealing at 600 °C. The directionality of the nanowires increased with increases in rotation speed. In addition, the structural formation and optoelectronic behavior of the CuCrO2 thin films have been studied by X-ray powder diffraction studies, transmission electron microscopy, field emission scanning electron microscopy, and UV-vis spectroscopy. The X-ray diffraction studies revealed a delafossite properties of the CuCrO2. The electrical conductivity in the parallel and vertical directions of the films produced at 2000–3000 rpm differed by two to three orders of magnitude. The optical transmittance properties of the CuCrO2 thin films were improved by increasing the rotation speed.

Summary
Metal oxides are a class of materials with a wide range of characteristics that are becoming increasingly used in a variety of applications. Transparent conducting oxides (TCO) are special semiconductors combining electrical conductivity and visible-range transparency in a single material [3]. They are used in a wide range of optoelectronic applications, such as photovoltaic cells, solar cells, flat panel displays, and gas sensors, and light-emitting diodes [4,5,6,7]. Electrospinning is more interesting because it is conducted at room temperature [29] It is a simple technique for nanowire preparation [30]. A polymer gel solution retained by its surface tension at the end of a tube is subjected to an electric field in the electrospinning. The results indicated that the rotation speed and temperature influence the morphological structure of CuCrO2 nanowires
