  • Electrical characterization and cathodoluminescence microanalysis of AlN/GaN heterostructures 
    HUBBARD, S. M.; PAVLIDIS, D.; VALIAEV, V.; STEVENS-KALCEFF, M. A.; TIGINYANU, I. M. (ELSEVIER, 2002)
    Low-pressure MOCVD is used to grow AlN/GaN MIS-type heterostructures with AlN thickness between 3 and 35 nm. The two-dimensional electron gas (2DEG) Hall mobility was found to decrease with AlN thickness. The measured room ...
  • Fröhlich modes in gan columnar nanostructures 
    TIGINYANU, I. M.; SARUA, A.; IRMER, G.; MONECKE, J.; HUBBARD, S. M.; PAVLIDIS, D.; VALIAEV, V. (American Physical Society, 2001)
    GaN columnar nanostructures fabricated by electrochemical dissolution of bulk material have been studied by micro-Raman spectroscopy. The anodization induces an increase in the intensity of Raman scattering accompanied by ...
