Difference frequency Fermi resonance interface modes in organic multilayer structures

Difference Fermi resonance interface modes occur in layered molecular materials when two excitations on one side of an interface differ in energy by an amount that matches approximately the energy of an excitation to which they are coupled on the other side, provided that the mismatch (detuning) is less in magnitude than the non-linear coupling across the interface. Under this resonance conditi...

Organic and Inorganic Dyes in Polyelectrolyte Multilayer Films

Polyelectrolyte multilayer films are a versatile functionalization method of surfaces and rely on the alternated adsorption of oppositely charged species. Among such species, charged dyes can also be alternated with oppositely charged polymers, which is challenging from a fundamental point of view, because polyelectrolytes require a minimal number of charges, whereas even monovalent dyes can be...

Molecular dynamic simulations of the sputtering of multilayer organic systems

Sputtering of organic overlayers has been modeled using molecular dynamics computer simulations. The investigated systems are composed of benzenemolecules condensed into one, two and three layers on anAg{1 1 1} surface. The formed organic overlayers were bombarded with 4 keV Ar projectiles at normal incidence. The development of the collision cascade in the organic overlayer was investigated. T...

Multilayer thin film encapsulation for organic light emitting diodes

A transparent and effective thin film encapsulation (TFE) based on a multilayer structure is demonstrated. Alternate films of amorphous and crystalline film forming organic materials have been investigated to create complicated diffusion pathways for oxygen and water vapour, which was reflected in their increased barrier properties. These layers are further protected by an inorganic barrier coa...
