Abstract
Probing the electronic structure of Mn doped SnO2 is crucial due to its enormous applications including optoelectronics, superconductors, gas sensors etc. In the present study we have investigated the complete electronic structure of the 10% Mn doped SnO2 thin film on Si (001) substrate. X-ray diffraction confirms the single-phase growth with decreasing crystallite size with Mn doping. X-ray photoemission spectroscopic study reveals the presence of dominant Sn4+ with minor Sn2+ valence state owing to oxygen deficiency resulting in Mn4+ and Mn2+ state in our grown film. Our resonant photoemission study reveals the origin of different bands near Fermi level, which can be further tuned for various fundamental properties.
