- W2906176722 abstract "The current research aims to investigate transparent conducting properties of In4Sn3O12 related compounds. Undoped and M-doped In4Sn3O12 with the formula In4+xSn3-2xMxO12 (Mx = Nb0.5 and Ta0.5) have been successfully synthesized by solid state reaction as confirmed by powder X-ray diffraction. Interestingly, only the composition with x = 0.5 could be achieved without impurity. The oxidation states of all elements were identified by X-ray photoelectron spectroscopy to be In3+, Sn4+, Nb5+, and Ta5+. The larger optical band gap energies were obtained in doped samples, which agree with the results from DFT calculations. Although the conductivity of In4Sn3O12 is relatively high, those of In4.5Sn2Nb0.5O12 and In4.5Sn2Ta0.5O12 are much lower. To investigate the conduction mechanism, the conductivity of the samples after heat treatment in N2 was studied. The improved conductivity after such annealing along with the results from X-ray photoelectron spectroscopy suggest that the major charge carriers are electrons created from oxygen vacancies in the lattice. The results from computational calculations indicate that Nb, Ta, and for comparison, Sb substitutions do not significantly change the band structure nor the carrier mobility. However, Sb could lower the oxygen vacancy formation energy which might be the reason of lower resistivity in Sb substituted In4Sn3O12. Besides the oxygen vacancy formation energy, the nature of donor states is important in determining the electrical conduction in the samples." @default.
