Abstract
The potential profiles, wave functions, energies of surface subbands, and lifetimes of positrons in aluminum nanofilms bordering insulators (solid inert gases and SiO2) have been calculated self-consistently in the previously proposed models. The size effects and the influence of the effective masses of electrons and positrons on the energy and annihilation characteristics in systems with double potential wells formed by image potentials have been investigated. The possibility of localizing a positronium atom in nanosandwiches has been discussed.
