Abstract

The effect of metal electrodes on methylene-methyliminomethyl formamidine (MMF) molecule has been calculated by Density functional analysis using Gaussian09 program package. The various applied electric fields (0.00 – 0.26 VÅ-1) altered the geometrical parameters and the corresponding electrostatic and transport properties of the molecule has been analyzed. The variations in the atomic charges (MPA, NPA) of the molecule for the various applied electric fields have been compared. The HOMO-LUMO gap of the molecule for zero bias is 1.904 eV, as the field increases this gap decreases to 0.272 eV. The ESP shows the potential difference between charges accumulated of the molecule for various applied electric fields. The applied electric field polarizes the molecule, in consequence of that the dipole moment of the molecule decreases from 9.65 to 8.82 Debye. The small decrease of dipole moment shows that the molecule exhibits smaller conductivity.
