摘要
We report on ultraviolet Raman spectroscopy of InxGa1-xN thin films grown on sapphire by metal-organic chemical vapor deposition. The A(1)(LO) and E-2 phonon mode behavior was investigated over a large compositional range (0 <x <0.50). Compelling evidence is presented for one-mode behavior for the A(1)(LO) phonon, and data suggestive of two-mode behavior are presented for the E-2 phonon. (C) 2001 American Institute of Physics.
