“…Therefore, more and more efforts are performed in order to develop methods for nano-or microstructuring of TiO 2 thin films. The commonly employed post-treatment methods are laser irradiation [12,13], ion bombardment [14], and electron beam irradiation [15]. Although few works on the electron irradiation effect in a TiO 2 films are available, most of them deal with the improvement of the TiO 2 photoactivity as a function of the absorbed radiation dose (MGy) [16].…”
