Abstract
The optical and electrical properties of films made of nanoparticles of indium tin oxide (ITO) are widely studied because of the significance of this material for transparent electrodes, smart windows, and nonlinear optics components. In this work, a systematic study of the resistance in ITO nanocrystalline films, as a function of post-fabrication parameters, such as the temperature and time of annealing, has been performed. A tunability of the resistance with the annealing parameters, in a range of three orders of magnitude, has been demonstrated. The optical properties of the nanocrystalline films were also evaluated as a function of the same parameters. Results show a different influence of temperature and time on the modification of the absorption properties. Temperature and time can be used synergistically to obtain thin films with desired optical and electrical properties through post-fabrication treatments.File | Dimensione | Formato | |
