Abstract

We report on surface topographical, chemical and optoelectronic properties of sub-stoichiometric MoO3 thin films, MoO3-x, made by pulsed laser deposition. MoO3-x is a promising candidate for a sustainable intermediate band material. The absorption coefficient for photon energies below the MoO3 bandgap increases for films made in oxygen poor environments, and is explained by the occurrence of states in the bandgap related to oxygen vacancies and to phase mixtures of MoO3-x compositions with 0<x<1 in the films. The MoO3-x film properties are closely linked to the film deposition parameters.
