Journal ArticleDOI
Self-Organization of TiO2 Nanoparticles in Thin Films
Shelly D. Burnside,Valery Shklover,Christophe Jean Alexandre Barbe,Pascal Comte,Francine Arendse,Keith G. Brooks,Michael Graetzel +6 more
TL;DR: In this paper, X-ray analysis showed the anatase crystal phase of the nanocrystalline titanium dioxide colloids to be primarily the rodlike particle morphology after growth at lower temperatures and the formation of principally truncated tetragonal or tetrahydral bipyramidal nanocrystites following growth at higher temperatures.
Journal ArticleDOI
Surface Photovoltage Spectroscopy of Dye-Sensitized Solar Cells with TiO2, Nb2O5, and SrTiO3 Nanocrystalline Photoanodes: Indication for Electron Injection from Higher Excited Dye States
Frank Lenzmann,Jessica Krueger,Shelly D. Burnside,Keith G. Brooks,Michael Grätzel,Doron Gal,and Sven Rühle,David Cahen +7 more
TL;DR: In this article, the onset wavelengths of the surface photovoltage (SPV) in dye-sensitized solar cells (DSSCs) with different mesoporous, wideband gap electron conductor anode materials, viz., TiO2 (anatase), Nb2O5 (amorphous and crystalline), and SrTiO3, using the same Ru bis-bipyridyl dye for all experiments, are different.
Journal ArticleDOI
Orientation of rapid thermally annealed lead zirconate titanate thin films on (111) Pt substrates
Keith G. Brooks,Ian M. Reaney,Radosveta D. Klissurska,Yuhong Huang,L. A. Bursill,Nava Setter +5 more
TL;DR: In this article, the effects of pyrolysis temperature, post-pyrolyisation thermal treatments, and excess lead addition on the growth and orientation of lead zirconate titanate thin films prepared from organometallic precursor solutions by spin coating on (111) oriented platinum substrates and crystallized by rapid thermal annealing was investigated.
Journal ArticleDOI
Fabrication and characterization of PZT thin-film vibrators for micromotors
Paul Muralt,Markus Kohli,Thomas Maeder,Andrei L. Kholkin,Keith G. Brooks,Nava Setter,R. Luthier +6 more
TL;DR: In this article, a micromotor driven by a piezoelectric PZT (PbZrxTi1-xO3) thin film has been characterized and the amplitudes of the membrane deflections are measured by means of laser interferometry.
Journal ArticleDOI
Self-polarization effect in Pb(Zr,Ti)O3 thin films
TL;DR: In this paper, the self-polarization effect of Pb(Zr,Ti)O3 (PZT) thin films deposited by sol-gel and magnetron sputtering techniques was investigated.
