Abstract: We have performed {\it ab-initio} electronic structure calculations todetermine the evolution of the electronic structure of WO$3$ with Na doping.Na doping introduces an additional electron when introduced into WO$3$. Theensuing electronic structure of Na doped WO$3$, we find, is very similar tothe electronic structure of an electron introduced into WO$3$, thus clarifyingthe role of the impurity potential due to Na. While the electronic structure ofNaWO$3$ allows a rigid band like description over a certain energy range,modifications introduced in the electronic structure can be related back to theelectron due to Na and not the impurity potential that one generally believesto be responsible.
