Local states in organic materials: charge transport and localization

The origin of local states capable of localizing charge carriers in molecular materials is discussed. The classical electrostatic model is employed to estimate the energies of chemical and structural traps in molecular materials, with particular attention being paid to polycrystalline and amorphous...

Summary:The origin of local states capable of localizing charge carriers in molecular materials is discussed. The classical electrostatic model is employed to estimate the energies of chemical and structural traps in molecular materials, with particular attention being paid to polycrystalline and amorphous low-molecular weight and polymeric materials
