BARRERA, Claudia P.; QUIROZ, Heiddy P.; REY, Rafael R.  e  DUSSAN, Anderson. DEPENDENCE OF PHOTONIC BAND GAP ON THE RADIUS OF TRACES IN TiO ₂ NANOSTRUCTURES. Momento [online]. 2017, n.55, pp.26-35. ISSN 0121-4470.  https://doi.org/10.15446/mo.n55.66141.

We study the evolution of the photonic gap present in TiO2 traces, these structures appear in the Ti-TiO2 interface during titania nanotubes formation. Traces can be modeled like photonic crystal because the dielectric function varies periodically in a bi-dimensional space. We conducted a theoretical study based on experimental measurements in traces of TiO2. The study was developed using a plane wave expansion method. This work is a first attempt to introduce photonic gap engineering, which could have technological interests.
