Photoelectron spectroscopy studies of Ru(dchpyH2)(sub 2)(NCS)2/Cul and Ru(dcbpyH2)(sub 2)(NCS)2/CuSCN interfaces for solar cell applications

Article Abstract:

The electronic structure of the wide band gap hole conductors CuI and CuSCN in contact with an organic dye cis-bis(4,4'-dicarboxy-2,2'-bipyridine)bis(isothiocyanato)ruthenium-(II)), (Ru(dcbpyH2)(sub 2)(NCS)2) are analyzed with photoelectron spectroscopy. The experiments revealed the specific interaction between the NCS groups of the dye molecules and the CuI and CuSCN surfaces.

Probing organisation and structural characteristics of alkanethiols adsorbed on gold and of model alkane compounds through their valance electronic structure: An ultra violet photoelectron spectroscopy study

Article Abstract:

An ultra violet photoelectron spectroscopy (UPS) study of saturated alkane chains in various configurations and confirmtions is reported. Angular dependent measurements and investigations on the photoelectron attenuation length have evidenced very fine structual differences between films obtained on deposited gold films, annealed gold films, and gold single crystals.

High-resolution electron energy loss spectroscopy investigation of the vibrational structure and order of an octadecanethiol monolayer on gold substrates

Article Abstract:

The vibrational spectra induced by electron beam from octadecanethiol monolayers adsorbed on gold was reported to study the structure of the layers, through an analysis of the interaction mechanisms between the electrons and these organic ultrathin films. The angular distribution of the elastic peak was very broad, nearly purely impact-like.
