This paper describes a promising n-type doping system with high performance for thermoelectric applications. By introducing the polar triethylene glycol (TEG) side chain onto both fullerene host (PTEG1) and dopant (TEG-DMBI) materials, the TEG-DMBI d

Superconductivity in K3C60 and Rb3C60 surfaces

Publikováno v: ELECTRONIC PROPERTIES OF MOLECULAR NANOSTRUCTURES. :122-126

We present a detailed investigation of the surface electronic structure of solid K;CM, and Rb3C60 in connection with their electronic transport properties. The best conducting samples with the highest superconducting transition temperature T, have th

Strongly reduced band gap in a correlated insulator in close proximity to a metal

Publikováno v: Europhysics Letters. 40(2):177-182

Using a combination of photoelectron and inverse photoelectron spectroscopy, we show that the band gap in a monolayer of C-60 on a Ag surface is strongly reduced from the solid C-60 surface value. We argue that this is a result of the reduction of th

Excitons in C-60 studied by temperature-dependent optical second-harmonic generation

Publikováno v: Physical Review B. 52(24):17158-17164

The electric-dipole-forbidden T-1(1g) excitonic state of solid C-60 at hw=1.81 eV can be probed with a second-harmonic generation (SHG) experiment. We show that the SHG line shape depends strongly on the degree of rotational order. We observe a split

Fullerides - Superconductivity at the limit

Autor: Palstra, Thomas T. M.

Publikováno v: Nature Materials, 7(5), 350-351. Nature Publishing Group

The successful synthesis of highly crystalline Cs3C60, exhibiting superconductivity up to a record temperature for fullerides of 38 K, demonstrates a powerful synthetic route for investigating the origin of superconductivity in this class of material

International audience; In this paper, the important role of neutron spectroscopy for the study of the dynamics of C-60 molecules hosted inside single-walled carbon nanotubes (SWNT) is described. We find that the intramolecular vibrations of the full
