| Electron politics: Physicists probe organization at the quantum level Posted: 25 Apr 2012 11:36 AM PDT "Quantum critical points" (QCP) in exotic electronic materials can act much like polarizing "hot button issues" in an election. On either side of the QCP, electrons fall into line and behave as traditionally expected, but the new study finds traditional physical laws break down at the critical point itself.  |
| Laser blackout quirk important to future electronics? Posted: 25 Apr 2012 06:43 AM PDT Two lamps are brighter than one. This simple truism does not necessarily apply to lasers, as a team of scientists found out. When one laser is shining and next to it another laser is turned on gradually, complex interactions between the two lasers can lead to a total shutdown and no light is emitted anymore. For technologies connecting the fields of electronics and photonics, this result may be very important.  |
| Graphene boosts efficiency of next-gen solar cells Posted: 24 Apr 2012 05:51 PM PDT Scientists found that incorporating graphene increased the cell's conductivity, bringing 52.4 percent more current into the circuit.  |
| Improving on the amazing: Scientists seek new conductors for metamaterials Posted: 24 Apr 2012 09:17 AM PDT Scientists have designed a method to evaluate different conductors for use in metamaterial structures, which are engineered to exhibit properties not possible in natural materials.  |
| Scientists discover bilayer structure in efficient solar material Posted: 24 Apr 2012 09:07 AM PDT Detailed studies of one of the best-performing organic photovoltaic materials reveal an unusual bilayer lamellar structure that may help explain the material's superior performance at converting sunlight to electricity and guide the synthesis of new materials with even better properties.  |
