Organic dyes incorporating low-band-gap chromophores based on pi-extended benzothiadiazole for dye-sensitized solar cells

Mohammad Khaja Nazeeruddin, Filippo de Angelis

A series of new it-conjugated organic dyes (HKK-BTZ1, HKK-BTZ2, HKK-BTZ3 and HKK-BTZ4), comprising triphenylamine (TPA) moieties as the electron donor and benzothiadiazole moieties as the electron acceptor/anchoring groups, was synthesized for the use in d ...

Tuning the giant Rashba effect on a BiAg2 surface alloy: Two different approaches

Klaus Kern, Marco Grioni, Alberto Crepaldi, Emmanouil Frantzeskakis

We discuss two different approaches for tuning the giant spin-orbit splitting of a BiAg2 surface alloy. The first approach consists of electron doping by alkaline metal deposition in order to shift the energy position of the spin-split surface states, whil ...

Molecular Electrocatalysis for Oxygen Reduction by Cobalt Porphyrins Adsorbed at Liquid/Liquid Interfaces

Hubert Girault, Pierre-Alain Carrupt, Bin Su, Imren Hatay, Zdenek Samec

Molecular electrocatalysis for oxygen reduction at a polarized water/1,2-dichloroethane (DCE) interface was studied, involving aqueous protons, ferrocene (Fc) in DCE and amphiphilic cobalt porphyrin catalysts adsorbed at the interface. The catalyst, (2,8,1 ...

Electron trapping in substoichiometric germanium oxide

Alfredo Pasquarello, Peter Broqvist, Jan Felix Binder

Model structures of substoichiometric germanium oxide generated by ab initio molecular dynamics reveal a rich variety of bonding configurations, including threefold coordinated Ge and O atoms which correspond to valence alternation pairs. A sizable fractio ...

Concept of a Molecular Charge Storage Dielectric Layer for Organic Thin-Film Memory Transistors

Francesco Stellacci, Kislon Voitchovsky

A mixed self-assembled monolayer containing aliphatic and electron-accepting (C-60) components is employed as an ultrathin molecular gate dielectric to facilitate reversible, nonvolatile electronic memory functionality in organic transistors at low supply ...

Origin and manipulation of the Rashba splitting in surface alloys

Marco Grioni, Luca Moreschini

A novel method is demonstrated to tailor the electronic structure of high-Z surface alloys showing a giant Rashba splitting by means of electron doping. This aims for new model systems to study unconvential spin topologies and for possible applications in ...

Hybrid-functional calculations with plane-wave basis sets: Effect of singularity correction on total energies, energy eigenvalues, and defect energy levels

Alfredo Pasquarello, Peter Broqvist, Audrius Alkauskas

When described through a plane-wave basis set, the inclusion of exact nonlocal exchange in hybrid functionals gives rise to a singularity, which slows down the convergence with the density of sampled k points in reciprocal space. In this work, we investiga ...

Decay mechanisms of excited electrons in quantum-well states of ultrathin Pb islands grown on Si(111): Scanning tunneling spectroscopy and theory

Wolf-Dieter Schneider, François Patthey, I-Po Hong

Using low-temperature scanning tunneling spectroscopy at 5 and 50 K, we studied the linewidth of unoccupied quantum-well states in ultrathin Pb islands, grown on Si(111) on two different Pb/Si interfaces. A quantitative analysis of the differential conduct ...
