Magnesium incorporation in GaN grown by molecular-beam epitaxy
A pronounced dependence of Mg incorporation on surface polarity was observed in a series of Mg step-doped epitaxial GaN layers grown by rf-plasma-assisted molecular-beam epitaxy. Incorporation was studied for both ~0001!, or Ga-polarity and (0001̄) or N-polarity orientations. Up to a factor of 30 times more Mg was incorporated in Ga-polarity layers under certain conditions, as determined by seco...

متن کاملRealization of Cu-Doped p-Type ZnO Thin Films by Molecular Beam Epitaxy.
Cu-doped p-type ZnO films are grown on c-sapphire substrates by plasma-assisted molecular beam epitaxy. Photoluminescence (PL) experiments reveal a shallow acceptor state at 0.15 eV above the valence band edge. Hall effect results indicate that a growth condition window is found for the formation of p-type ZnO thin films, and the best conductivity is achieved with a high hole concentration of 1...
متن کاملGrowth and morphology of Er-doped GaN on sapphire and hydride vapor phase epitaxy substrates
We report the morphological and compositional characteristics and their effect on optical properties of Er-doped GaN grown by solid source molecular beam epitaxy on sapphire and hydride vapor phase epitaxy GaN substrates. The GaN was grown by molecular beam epitaxy on sapphire substrates using solid sources ~for Ga, Al, and Er! and a plasma gas source for N2. The emission spectrum of the GaN:Er...
