| Material rivaling graphene may be mined out of rocks Posted: 12 Mar 2014 10:26 AM PDT Will one-atom-thick layers of molybdenum disulfide, a compound that occurs naturally in rocks, prove to be better than graphene for electronic applications? There are many signs that might prove to be the case. But physicists have shown that the nature of the phenomena occurring in layered materials are still ill-understood and require further research.  |
| Signal control with light frequencies Posted: 12 Mar 2014 05:25 AM PDT Light waves have the potential to boost the efficiency of conventional electronics by a factor of 100,000. Researchers describe how this vision may one day become a reality. In their scenario, one would exploit the electric field of laser light to control the flow of electrons in dielectric materials, which, in turn, may modulate transmitted light and switch current in electronic circuits at light frequencies.  |
