GaN epitaxial growth on sapphire (0 0 0 1): The role of the substrate nitridation

Nicolas Grandjean

The nitridation of sapphire substrates was monitored in situ by reflection high-energy electron diffraction. The evolution of the lattice-mismatch evidences the formation of an AIN relaxed layer when exposing the sapphire surface heated at 850 degrees C to ...

Degradation of microgun-pumped blue lasers

Jean-Daniel Ganière

Microgun-pumped blue lasers with lasing thresholds in the 4-20 kW/cm(2) range for temperatures between 83 and 225 K were fabricated by molecular beam epitaxy. The devices exploit graded index, separate confinement Zn1-xCdxSe/ZnSe heterostructures and use a ...
