Resonant defect states of transparent conductive oxide SnO2:Ta revealed by excitation wavelength-dependent Raman spectroscopy and hybrid functional DFT calculations Excitation wavelength-dependent Raman spectroscopy, optical spectroscopy, and density functional theory (DFT) calculations with hybrid functionals were used to analyse the electronic structure of defects in transparent conductive oxide SnO2:Ta (1.25 at.% Ta) thin films.

The compositional, optical and structural stability of transparent conductive oxide SnO2:Ta (1.25 at.% Ta) thin films at 650 °C and 800 °C in air was studied under isothermal conditions. After the high-temperature treatment, the element composition and the optical spectra of the material were unchanged. The
