Biomolecular processes between dye molecules and polycyclic aromatic hydrocarbons on the surface of a semiconductor-dielectric structure

Abstract

The bimolecular processes of T-T annihilation and excimer formation of complex organic molecules adsorbed on semiconductor-dielectric structures are studied. The adsorption of molecules on a solid surface is ascertained to be island in character. It is found that the efficiency of bimolecular processes between adsorbed complex organic molecules is affected by the charge of slow traps on the semiconductor-dielectric interface, the oxide layer thickness, and the concentration of adsorbed water molecules.
