Neuartige Lichtquelle zum Blick ins Innere von Heusler-Materialien

Wissenschaftlern der Johannes Gutenberg-Universitaet Mainz ist es gelungen, in die Struktur von Heusler-Materialien vorzudringen und das Verhalten der Elektronen zu beobachten. Sie verwenden dazu eine besondere Form der Photoelektronenspektroskopie, die es moeglich macht, viel tiefer als bisher in die Materie vorzudringen und die elektronische Beschaffenheit zu untersuchen.

'Oscar Madison' approach to solar cells may outshine 'Felix Unger' design

An international team of researchers has for the first time demonstrated that random, haphazardly grown silicon nanowires can significantly boost the power-producing capabilities of solar cells by trapping a broad spectrum of light waves and capturing sunlight streaming in from a wide variety of angles.

European project achieves major milestone towards fabricating silicon photonics circuits in CMOS foundries

By demonstrating for the first time a 40Gbit/s optical modulator in silicon with a record extinction ratio of 10dB (the power difference between the 1 and 0 data levels), members of the HELIOS Project accomplished one of the key project goals needed to build and optimize the entire supply chain for fabricating complex functional silicon- photonics devices from design to the process level.
