Pressure dependence of the large-polaron transport in anatase TiO2 single crystals

László Forró, Arnaud Magrez, Richard Gaal, Helmuth Berger, Jacim Jacimovic, George Cristian Vaju, Radomir Zikic

We have measured the pressure and temperature dependences of the resistivity and the thermoelectric power of anatase, TiO2. The resistivity varies with T-3 at high temperatures, and its absolute value is in the 1 Omega cm range. Below 60 K, the resistivity ...

Defects and localization in chemically-derived graphene

László Forró, Arnaud Magrez, Andrzej Sienkiewicz, Richard Gaal, Luka Ciric, Jacim Jacimovic, George Cristian Vaju

We have performed electron spin resonance (ESR) measurements on a large assembly of graphene oxide (GO) and reduced graphene oxide (RGO) flakes. In GO samples the Curie tail is coming from 1.4 x 10(18) cm(-3) of localized spins. Although reduction of GO wa ...

Synthesis, electrical resistivity, thermo-electric power and magnetization of cubic ZnMnO3

László Forró, Arnaud Magrez, Andrzej Sienkiewicz, Richard Gaal, Rita Smajda, Jacim Jacimovic, Zlatko Mickovic, George Cristian Vaju

Cubic ZnMnO3 powder in the form of well-crystalline nanoflakes have been synthesized at low temperatures from a nitrate precursor. The electrical properties of cubic ZuMnO(3) samples have been established by DC resistivity (rho) and thermo-electric power ( ...
