Growth of CaMnO Ruddlesden-Popper structured thin films using Combinatorial Substrate Epitaxy
M. Lacotte, A. David, D. Pravarthana +6
The local epitaxial growth of pulsed laser deposited CaMnO films on polycrystalline spark plasma sintered SrTiO substrates was investigated to determine phase forma…
BiFeO3/La0.7Sr0.3MnO3 heterostructures deposited on Spark Plasma Sintered LaAlO3 Substrates
D. Pravarthana, M. Trassin, Jiun Haw Chu +5
Multiferroic BiFeO3 (BFO) / La0.7Sr0.3MnO3 heterostructured thin films were grown by pulsed laser deposition on polished spark plasma sintered LaAlO3 (LAO) polycrystalline substrat…
High-throughput synthesis of thermoelectric CaCoO films
D. Pravarthana, O. I. Lebedev, D. Chateigner +3
Properties of complex oxide thin films can be tuned over a range of values as a function of mismatch, composition, orientation, and structure. Here, we report a strategy for growin…
Enhanced thermoelectric performance in spark plasma textured bulk n-type BiTe2.7Se0.3 and p-type Bi0.5Sb1.5Te3
Shekhar D. Bhame, Dhanapal Pravarthana, Wilfrid Prellier +1
Bulk p and n-type bismuth telluride were prepared using spark plasma texturization method. The texture development along the uniaxial load in the 001 direction is confirmed from bo…
Growth and texture of Spark Plasma Sintered Al2O3 ceramics: a combined analysis of X-rays and Electron Back Scatter Diffraction
Dhanapal Pravarthana, D. Chateigner, L. Lutterotti +7
Textured alumina ceramics were obtained by Spark Plasma Sintering (SPS) of undoped commercial a-Al2O3 powders. Various parameters (density, grain growth, grain size distribution) o…
