Abstract

We report on surface topographical, chemical and optoelectronic properties of sub-stoichiometric MoO₃ thin films, MoO_3-x, made by pulsed laser deposition. MoO_3-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 MoO_3-x compositions with 0<x<1 in the films. The MoO_3-x film properties are closely linked to the film deposition parameters.
