Doping Nature of Native Defects in 1T-TiSe2

The transition-metal dichalcogenide 1T-TiSe2 is a quasi-two-dimensional layered material with a charge density wave (CDW) transition temperature of T-CDW approximate to 200 K. Self-doping effects for crystals grown at different temperatures introduce struc ...

Study of bending reliability and electrical properties of platinum lines on flexible polyimide substrates

Nico de Rooij, Danick Briand, Jérôme Courbat, Francisco Molina Lopez

We have experimentally studied the variation in electrical resistance of flexible platinum lines patterned on polyimide foil when they are subjected to circular bending constraints. The lines were patterned by means of standard photolithography and sputter ...

Effect of Magnetic Ion Doping on Structural, Electric and Relaxor Properties of Pb (Fe2/3W1/3) O-3 Multiferroic Ceramics

Barbara Maraston Fraygola

Single-phase Pb(Fe2/3W1/3)O3 (PFW) multiferroic ceramics doped with magnetic ions were fabricated using a modified B-site precursor method. Dielectric response was investigated over a wide range of temperature and frequency. Doping did not modify the chara ...

Electrical property measurements of Cr-N codoped TiO2 epitaxial thin films grown by pulsed laser deposition

László Forró, Arnaud Magrez, Richard Gaal, Jacim Jacimovic

The temperature dependent resistivity and thermo-electric power of Cr-N codoped TiO2 were compared with that of single element N and Cr doped and undoped TiO2 using epitaxial anatase thin films grown by pulsed laser deposition on (100) LaAlO3 substrates. T ...

Partially disordered spin structure in Ag_{2}CrO_{2} studied with μ^{+}SR

Martin Mansson, Krunoslav Prsa

The magnetism of a metallic two-dimensional triangular antiferromagnetic (AF) compound, Ag2CrO2, has been investigated by muon-spin rotation and relaxation (mu+SR) using a powder sample in the temperature range between 1.8 and 40 K. Below T-N = 24 K, a muo ...

Tuneable PTC effect in polymer-wax-carbon composite resistors

Peter Ryser, Thomas Maeder, Caroline Jacq, Ludivine Ammon

The resistivity dependence on temperature of composite resistors made of carbon fillers dispersed in an organic matrix are known to be strongly affected by the matrix thermal expansion. High positive temperature coefficient (PTC) effects, i.e. essentially ...
