| Finding Achilles' heel of GaN-based LEDs in harsh radiation environments Posted: 08 Dec 2014 07:54 AM PST Proton irradiation of gallium nitride causes more damage in p-type material than n- doped layers, scientists have discovered. This unexpected finding is important for the application of GaN-based devices in extreme environments.  |
| New technique allows low-cost creation of 3-D nanostructures Posted: 08 Dec 2014 04:45 AM PST Researchers have developed a new lithography technique that uses nanoscale spheres to create 3-D structures with biomedical, electronic and photonic applications. The new technique is less expensive than conventional methods and does not rely on stacking two-dimensional patterns to create 3-D structures.  |
