Tuning of Structural and Morphological Characteristics of V<sub>2</sub>O<sub>5</sub> Thin Films Using Low Energy 16 keV N + for Optical and Wetting Applications
Abstract
<jats:p>Effect of nitrogen (N<jats:sup>+</jats:sup>) ion implantation on the morphological, structural, optical, and compositional properties of vanadium pentoxide (V<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub>) thin films grown on glass substrates is studied. Surface morphology shows the formation of grains and the growth dynamics is governed by roughness (<jats:italic>α</jats:italic>) and growth (<jats:italic>β</jats:italic>) exponents. X-ray diffraction studies reveal that V<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub> exists in a hybrid form, with properties of both the orthorhombic and tetragonal phases. Ion implantation induces defects and strain in V<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub> thin films causing a reduction in crystalline properties and deformation in the <jats:italic>β</jats:italic>-phase with a corresponding change in crystallite size. Contact angle wetting properties are found to be co-related with fractal growth of the films under ion implantation. Oxygen vacancies and electron scattering/trapping centres are revealed to have increased after N<jats:sup>+</jats:sup> implantation, leading to a smaller bandgap in the thin films. The benefits of decreasing the optical band-gap of V<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub> thin films for optical applications are outlined in the present work.</jats:p>
