|Title:||Deeper Understanding of Interstitial Boron-Doped Anatase Thin Films as A Multifunctional Layer Through Theory and Experiment||Authors:||Quesada Cabrera, Raúl||UNESCO Clasification:||2307 Química física||Issue Date:||2018||Journal:||Journal of Physical Chemistry C||Abstract:||Thin films of interstitial boron-doped anatase TiO2, with varying B concentrations, were deposited via one-step atmospheric pressure chemical vapor deposition (APCVD) on float glass substrates. The doped films showed a remarkable morphology and enhanced photoactivity when compared to their undoped analogues. The TiO2:B films also presented enhanced conductivity and electron mobility as measured by a Hall effect probe as well as a high adherence to the substrate, stability and extended lifetime. The structure and composition of the different samples of TiO2:B films were studied by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and dynamic secondary ion mass spectrometry (D-SIMS). Hybrid density functional theory was used to explore the defect chemistry of B-doped anatase and to understand the experimental results.||URI:||http://hdl.handle.net/10553/107986||ISSN:||1932-7447||DOI:||10.1021/acs.jpcc.7b11142||Source:||Journal Of Physical Chemistry C [ISSN 1932-7447], v. 122, p. 714-726|
