Query: Electronic properties of the Rutile-type dioxide SnO2 material doped by
  sulfur element: DFT study   In this work, we study the effect of doping the Rutile-type dioxide SnO2
material by the non-metal Sulfur (S) atoms on the electronic properties. In
fact, we have used the ab-initio method applied on the basis of the Density
Functional Theory (DFT) using the Quantum Espresso code. Through the density of
states and the band structure calculations for different concentrations have
been deduced. When doping the SnO2 material with 6% of Sulfur (S), we found a
perfect symmetry between up and down spin states in the total DOS confirming
the non-magnetic behavior of this material doped SnO2 with 6% of Sulfur. It is
also worth to note that the SnO2 material doped with 6% of Sulfur, exhibits a
semiconductor of the P-type. Moreover the band gap decreases when increasing
the concentration of doping the SnO2 by Sulfur. Our results are in good
agreement with the existing literature both experimental and theoretical.
