Magnetic characterization of oblique angle deposited Co/CoO on gold nanoparticles
Johanna K. Jochum, Thomas Saerbeck, Vera Lazenka +6
The influence of a patterned substrate on obliquely deposited, exchange biased Co/CoO films was studied. It was found that substrates decorated with nanoparticle patterns provide t…
Perovskite-perovskite tandem photovoltaics with optimized bandgaps
Giles E. Eperon, Tomas Leijtens, Kevin A. Bush +24
We demonstrate four and two-terminal perovskite-perovskite tandem solar cells with ideally matched bandgaps. We develop an infrared absorbing 1.2eV bandgap perovskite, $FA_{0.75}Cs…
Transition from anomalous kinetics towards Fickian diffusion for Si dissolution into amorphous Ge
Z. Balogh, Z. Erdelyi, D. L. Beke +7
Over the last years several experimental and theoretical studies of diffusion kinetics on the nanoscale have shown that the time evolution differs from the classical Fickian law (k…
