New diamond structures produce bright luminescence for quantum cryotography and biomarkers applications

Germanium defects in a diamond crystal lattice act as a reliable source for single photons, new research shows. The results are reported in Scientific Reports and provide a promising new route to building components for quantum cryptography and biomarkers. Pure diamonds are naturally colorless, but gaps in the crystal structure or impurities of other...

Nanowire quantum dot solar cells: oxide layer boosts performance

Attempts to improve solar cells can seem a balancing act, as optimising one variable can compromise another. The introduction of nanowires to colloidal quantum-dot solar cells (CQDSCs) aroused interest as a means of improving a limitation in the charge-collection layer thickness. However the high nanowire surface area brings other inhibiting factors....
