11 p, 4.4 MB Pulsed laser deposition of epitaxial non-doped PbTiO3 thin films from Pbo-TiO2 mosaic targets / Sakai, Joe (Institut Català de Nanociència i Nanotecnologia) ; Caicedo Roque, Jose Manuel (Institut Català de Nanociència i Nanotecnologia) ; Vales Castro, Pablo (Institut Català de Nanociència i Nanotecnologia) ; Padilla-Pantoja, Jessica (Institut Català de Nanociència i Nanotecnologia) ; Sauthier, Guillaume (Institut Català de Nanociència i Nanotecnologia) ; Santiso, José (Institut Català de Nanociència i Nanotecnologia)
PbTiO3 (PTO) suffers from difficulty in preparing high-density robust bulk ceramics, which in turn has been a bottleneck in thin films growth with physical vapor deposition (PVD) methods. In the present work, we prepared non-doped PTO thin films by a pulsed laser deposition (PLD) method with either a single PTO target or a mosaic target consisting of PbO and TiO2 pie-shaped pieces.

7 p, 1.3 MB Terahertz displacive excitation of a coherent Raman-active phonon in V2O3 / Giorgianni, Flavio (Paul Scherrer Institut (Suïssa)) ; Udina, Mattia (Università degli studi di Roma "La Sapienza". Department of Physics) ; Cea, Tommaso (IMDEA Nanoscience) ; Paris, Eugenio (Paul Scherrer Institut (Suïssa)) ; Caputo, Marco (Photon Science Division. Paul Scherrer Institute) ; Radovic, Milan (Photon Science Division. Paul Scherrer Institute) ; Boie, Larissa (ETH Zurich. Physics Department) ; Sakai, Joe (Institut Català de Nanociència i Nanotecnologia) ; Schneider, Christof W. (Paul Scherrer Institut (Suïssa)) ; Johnson, Steven Lee (ETH Zurich. Physics Department)
Nonlinear processes involving frequency-mixing of light fields set the basis for ultrafast coherent spectroscopy of collective modes in solids. In certain semimetals and semiconductors, generation of coherent phonon modes can occur by a displacive force on the lattice at the difference-frequency mixing of a laser pulse excitation on the electronic system.

11 p, 17.0 MB Stress-Induced In Situ Modification of Transition Temperature in VO Films Capped by Chalcogenide / Sakai, Joe (Institut Català de Nanociència i Nanotecnologia) ; Kuwahara, Masashi (National Institute of Advanced Industrial Science and Technology) ; Okimura, Kunio (Tokai University. Graduate School of Science and Technology) ; Uehara, Yoichi (Tohoku University. Research Institute of Electrical Communication)
We attempted to modify the monoclinic-rutile structural phase transition temperature (T ) of a VO thin film in situ through stress caused by amorphous-crystalline phase change of a chalcogenide layer on it. [...]

12 p, 2.8 MB Control of lateral composition distribution in graded films of soluble solid systems A1-xBx by partitioned dual-beam pulsed laser deposition / Sakai, Joe (Institut Català de Nanociència i Nanotecnologia) ; Caicedo Roque, Jose Manuel (Institut Català de Nanociència i Nanotecnologia) ; Vales Castro, Pablo (Institut Català de Nanociència i Nanotecnologia) ; Padilla-Pantoja, Jessica (Institut Català de Nanociència i Nanotecnologia) ; Sauthier, Guillaume (Institut Català de Nanociència i Nanotecnologia) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia) ; Santiso, José (Institut Català de Nanociència i Nanotecnologia)
Lateral compositionally-graded thin films are powerful media for the observation of phase boundaries aswell as for high-throughputmaterials exploration. We herein propose amethod to prepare epitaxial lateral compositionally-graded films using a dual-beampulsed laser deposition (PLD)method with two targets separated by a partition. [...]

24 p, 1.1 MB Persistent M2 phase in strongly strained (011)-oriented grains in VO2 films grown on sapphire (001) in reactive sputtering / Matsuoka, K. (Tokai University. Graduate School of Engineering) ; Okimura, Kunio (Tokai University. Graduate School of Engineering) ; Azhan, Nurul Hasnis (Universiti Kuala Lumpur British Malaysian Institute. Electrical Engineering Section) ; Zaghrioui, Mustapha (Laboratoire GREMAN) ; Sakai, Joe (Institut Català de Nanociència i Nanotecnologia)
We report on the first observation of the persistent M2 phase in strongly strained (011)-oriented grains in VO₂ films grown on Al₂O₃ (001) substrates by means of conventional rf reactive sputtering under adequate deposition conditions. [...]
