What is it about?
We show that low energy ions (150eV) can effectively dope titanium dioxide (anatase) and make it a good electrical conductor while preserving its transparency, such that N doped TiO2 can be used as transparent conductor electrode. We demostrate that the doping process by low energy ion implantation (only 1560 eV) does not change the crystal structure of the Anatase crystal.

Why is it important?
We show the effectiveness of low energy ion beam in doping titanium dioxide without changing is crystal structure. In our method, we can have very accurate control of the amount of dopant and the crystal structure of the film independently. So, crystal grain are not modified and the material does not become amorphous. So, the TCO performance was very interesting with respect to established materials, like ITO.
