Effects of the Sapphire Nitridation on the Polarity and Structural Properties of GaN Layers Grown by Plasma-Assisted MBE
Georgakilas, A.; Mikroulis, S.; Cimalla, V.; Zervos, Matthew; Kostopoulos, A.; Komninou, Ph; Kehagias, Th; Karakostas, Th (2001)The nitridation of the (0001) sapphire surface by a nitrogen rf-plasma source used in GaN molecular beam epitaxy has been investigated. Auger electron spectroscopy measurements were used to estimate the extent of the ...
