ABSTRACT
Generalized infrared spectroscopic ellipsometry over the wave-number range from 300 to 2000 cm[sup -1] is used for precise determination of the dielectric function, frequency, amplitude, and broadening parameters of 27 infrared active modes for polarization parallel to the growth surface of pentacene thin films obtained by molecular-beam deposition on glass. No in-plane anisotropy was detected, which is indicative for a random orientation of crystallites around the growth direction supporting previous x-ray diffraction results. © 2004 American Institute of Physics.

    Photoluminescence (PL) and x-ray diffraction (XRD) have been performed to examine the In/N ratio effect on the InN films. The PL of N-rich InN are more asymmetric, broadened, and have higher energy compared with In-rich ones. An important finding is that the N-rich and In-rich InN show a sharp...
