Ta 2 O 5 films, 10 and 100 nm in thickness, directly deposited on a Si substrate were investigated by using transmission Fourier-transform infrared spectroscopy. The samples were annealed in dry oxygen, wet oxygen and nitrogen atmospheres. The Ta-O phonon peaks in the infrared absorption spectra appeared at 210, 510 and 570 cm -1 in samples that were annealed at 700 and...
Polarized X-ray absorption near-edge structure (XANES) was studied for iodine L I -edge on the single crystal of (EDT-TTF(SC 18 ) 2 I 3 which has identical physical properties to the Langmuir-Blodgett (LB) films. The polarization dependence of XANES spectra showed that I; anions incline 10° from the conducting axis (b axis). Incorporating the present result into...
