英文摘要	Iron phthalocyanine molecule (FePc) thin films were deposited on Cu(100) and Si(100) substrates in sequential steps and the interface was characterized by means of scanning tunneling microscope, X-ray photoemission spectroscopy, and its sister technique ultra violet photoemission spectroscopy. At room temperature disordered structures are observed. However at elevated temperature approximate to 480 degrees C, a long range ordered pattern is noticed indicating the increase of diffusion of adsorbed molecules on the substrate surface. All the photoemission spectra exhibited a clear change and shift in the adsorbed peaks. The change in binding energy of C 1 s core level as revealed by X-ray photoemission spectroscopy is V-b = 0:18 eV. Our calculated work function of the clean Si (100) surface is 4.09 eV. The hole and electron injection barriers are estimated as 1.22 eV and -1.38 eV, respectively. Based on the measured quantities, the interface dipole potential is found to be -0.04 eV. A minute charge transferred from each adsorbed molecule to the substrate is estimated as ca: 8.565 x 10(-22) C. Besides, our computational density functional theory findings revealed a strong adsorbate-substrate interaction.
