Doping-dependent optical gain in GaN
We report on an investigation of the optical gain in undoped and Si-doped metal-organic vapor phase epitaxially grown GaN. For carrier densities around the Mott transition (at approximately 8×10...

Cluster formation by barrier discharge in simulated engine exhaust gas at high temperature
Experiments were performed to examine cluster formation when simulated engine exhaust gas passes through an atmospheric pressure plasma discharge cell at 180 °C. The gas composition included N2, N...

We have fabricated microlasers with disordered semiconductor nanoparticles. The physical mechanism of optical confinement is based on Anderson localization of light in micrometer-sized random media. Pulsed lasing occurs around 380 nm at room temperature under optical pumping. ©2000 American Institute of Physics.
