Anomalous anisotropic exciton temperature dependence in rutile TiO2

Elucidating the details of electron-phonon coupling in semiconductors and insulators is a topic of pivotal interest, as it governs the transport mechanisms and is responsible for various phenomena such as spectral-weight transfers to phonon sidebands and s ...

Interface Engineering of Perovskite Solar Cell Using a Reduced-Graphene Scaffold

Mohammad Mahdi Tavakoli, Soheil Hasanzadeh

Interface engineering of solar cell device is a prominent strategy to improve the device performance. Herein, we synthesize reduced-graphene scaffold (rGS) by using a new and simple chemical approach. In this regard, we synthesize 4 hollow structure of gra ...

Complex Magnetic Exchange Coupling between Co Nanostructures and Ni(111) across Epitaxial Graphene

Harald Brune, François Patthey, Stefano Rusponi, Marina Pivetta, Pietro Gambardella, Fabio Donati

We report on the magnetic coupling between isolated Co atoms as well as small Co islands and Ni(111) mediated by an epitaxial graphene layer. X-ray magnetic circular dichroism and scanning tunneling microscopy combined with density functional theory calcul ...

Out-of-Plane Alignment of Er(trensal) Easy Magnetization Axes Using Graphene

Harald Brune, Stefano Rusponi, Marina Pivetta, Jan Gui-Hyon Dreiser, Fabio Donati, Luca Gragnaniello, Giulia Elisabetta Pacchioni, Alberto Cavallin

We have studied Er(trensal) single -ion magnets adsorbed on graphene/Ru(0001), on graphene/Ir(111), and on bare Ru(0001) by scanning tunneling microscopy and X-ray absorption spectroscopy. On graphene, the molecules self -assemble into dense and well -orde ...

Transport, magnetic and vibrational properties of chemically exfoliated few-layer graphene

László Forró, Bálint Náfrádi, Péter Szirmai, Ferenc Simon, Bence Gábor Márkus

We study the vibrational, magnetic and transport properties of Few Layer Graphene (FLG) using Raman and electron spin resonance spectroscopy and microwave conductivity measurements. FLG samples were produced using wet chemical exfoliation with different po ...

Plasmon-Plasmon Hybridization and Bandwidth Enhancement in Nanostructured Graphene

Daniel Rodrigo Lopez

Graphene plasmonic structures with long-range layering periodicity are presented. Resonance energy scaling with the number of graphene layers involved in plasmonic excitation allows these structures to support multiple plasmonic modes that couple and hybri ...

Rutile TiO2-based perovskite solar cells

Michael Graetzel

A perovskite solar cell based on rutile TiO2 film was prepared and its photovoltaic performance was compared to an anatase TiO2-based perovskite solar cell. Rutile TiO2 nanoparticles with aspect ratio of 0.2 (20 nm wide and 100 nm long) were prepared by hy ...

Uniform TiO2/In2O3 surface films effective in bacterial inactivation under visible light

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

This study shows that the surface modification of TiO2 is an effective route to increase the TiO2 absorption in the visible region up to similar to 600 nm for photocatalytic applications. The In2O3 decorated TiO2 films on polyester obtained by reactive spu ...
