| 15 Apr | 2013 | Germanium is the laser material of the future
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 |
| 10 Sep | 2012 | Built-in germanium lasers could make computer chips faster - research on material produced by the SiGe epitaxy group published in Physical Review Letters in collaboration with the PSI and ETH Zürich in Switzerland, highlights the conditions under which a germanium laser could be realized. |

| 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). |
