Electronic Structure and Thermoelectric Properties of Pseudoquaternary Mg2Si1-x-ySnxGey-Based Materials
(2014)A theoretical study is presented on complex pseudoternary Bi-doped Mg2Si1-x-ySnxGey materials, which have recently been revealed to reach high thermoelectric figures of merit (ZT) of ∼1.4. Morphological characterization ...

Enhancing the nanoscratch resistance of pulsed laser deposited DLC films through molybdenum-doping
(2017)Pulsed laser deposition was used to grow DLC and molybdenum-doped DLC (DLC:Mo) films, with metal contents up to 3.2 at.%, on silicon substrates. The microstructural details of the films were investigated using X-ray ...

Picosecond ultrafast pulsed laser deposition of SrTiO3
(2015)SrTiO3 particle-composed films were grown on Si substrates via picosecond ultrafast pulsed laser deposition. We have investigated the effect of laser pulse repetition rate (0.2-8.2 MHz) and fluence (0.079-1.57 J cm-2) on ...

Solid-state synthesis of Mg 2Si via short-duration ball-milling and low-temperature annealing
(2013)In this work, a short duration ball-milling of elemental Mg and Si followed by a thermal treatment is suggested in order to synthesize magnesium silicide via solid-state reaction. The formation of magnesium silicide was ...

Stoichiometry issues in pulsed laser deposition of the ferromagnetic alloy NiMnSb
(Affiliation: NIRDO, BucharestAffiliation: MADIREL, Univ. Provence Centre St. Charles, Marseille, FranceAffiliation: Natl. Inst. Res. Devmt. Mat. Phy., BucharestAffiliation: Foundation for Res. and Technology, HELLAS, Inst. Electron. Structure and Laser, Heraklion, Crete, GreeceCorrespondence Address: Grigorescu, C.E.A.NIRDO, Bucharest, 2002)We report on the reproducible growth of stoichiometric thin films of ferromagnetic intermetallic compound NiMnSb by pulsed laser deposition (PLD) on various substrates. The films are grown at moderate temperature (around ...

Structural, magnetic, and electrical properties of NiMnSb thin films grown on InSb by pulsed-laser deposition
(2004)We report the growth of single-phase, stoichiometric polycrystalline thin films of the half-Heusler ferromagnet NiMnSb, predicted to be half-metallic, on single crystal InSb (100) substrates heated at 200°C by pulsed laser ...
