Pressure-induced tuning of phase transition and role of disorder in electrical transport properties of beta-Sr_xV_6O_15

László Forró, Richard Gaal, Ana Akrap, Neven Barisic

2007

Signatures of quantum criticality in the thermopower of Ba(Fe1-xCox)(2)As-2

László Forró, Richard Gaal, Stevan Arsenijevic

We demonstrate that the thermopower (S) can be used to probe the spin fluctuations (SFs) in proximity to the quantum critical point (QCP) in Fe-based superconductors. The sensitivity of S to the entropy of charge carriers allows us to observe an increase o ...

Effect of ultraviolet light irradiation on macroscopic single-walled carbon nanotube bundles

László Forró, Andrzej Kulik, Richard Gaal, Jin Won Seo, Csilla Mikó, Mirko Milas

2006

Separation of Orbital Contributions to the Optical Conductivity of BaVS3

László Forró, Helmuth Berger, Richard Gaal, Ana Akrap, Neven Barisic

2006

Electrical conductivity of multi-walled carbon nanotubes-SU8 epoxy composites

László Forró, Arnaud Magrez, Claudio Grimaldi, Richard Gaal, Marijana Mionic Ebersold

We have characterized the electrical conductivity of the composite which consists of multi-walled carbon nanotubes dispersed in SU8 epoxy resin. Depending on the processing conditions of the epoxy (ranging from non-polymerized to cross-linked), we obtained ...

Anisotropic transport properties of tungsten disulfide

Helmuth Berger, László Forró, Bálint Náfrádi, Richard Gaal, Jacim Jacimovic, Andrea Pisoni

Single crystals of WS2 were prepared by chemical vapor transport method using sulfur as a transport agent. Measurements of electrical resistivity, Seebeck coefficient and thermal conductivity as a function of temperature, along the in-plane and the out-of- ...

Defects and localization in chemically-derived graphene

László Forró, Arnaud Magrez, Andrzej Sienkiewicz, Richard Gaal, Jacim Jacimovic, Luka Ciric, 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 ...
