Synthesis of Orthorhombic Tin Dioxide Nanowires in Track Templates

Abstract

Electrochemical deposition into a prepared SiO2/Si-p ion track template was used to make orthorhombic SnO2 vertical nanowires (NWs) for this study. As a result, a SnO2-NWs/SiO2/Si nanoheterostructure with an orthorhombic crystal structure of SnO2 nanowires was obtained. Photoluminescence excited by light with a wavelength of 240 nm has a low intensity, arising mainly due to defects such as oxygen vacancies and interstitial tin or tin with damaged bonds. The current–voltage characteristic measurement showed that the SnO2-NWs/SiO2/Si nanoheterostructure made this way has many p-n junctions. © 2024 by the authors. --//-- This is an open-access article Baimukhanov, Z.; Dauletbekova, A.; Junisbekova, D.; Kalytka, V.; Akilbekov, A.; Akylbekova, A.; Baubekova, G.; Aralbayeva, G.; Bazarbek, A.-D.; Usseinov, A.; et al.
