Researchers at the Politecnico together with the ETH Zurich and the Paul Scherrer Institute (Switzerland) have demonstrated how germanium can be transformed into a laser material. By making micro-bridges of germanium in which the reduction of the cross-section of the bridge at a constriction concentrates the pre-existing thermal stress left behind by the growth process, the bandgap is modified in a way which turns germanium into an efficient light emitter.
The research is published in Nature Photonics

|24 Jul||2012||The Positron Group has published an advanced study on Hybrid Solar Cells in collaboration with the IIT (Italian Institute of Technology).
Hybrid solar cells are a combination of organic and inorganic materials. This new generation of thin-film is based on a very favourable price/performance ratio and the possibility to manufacture flexible and large-area modules. Positron Annihilation Spectroscopy using a variable-energy positron beam has been employed for the first time in this field in order to obtain depth-resolved data to study the infiltration of a conductive polymer (P3HT) into a mesoporous skeleton of titania. It has been possible to understand the reason of the improvement the device performance by engineering the hybrid interface using an inexpensive and transparent interlayer (4-mercaptopyridine).
