Abstract

The characteristics of RuO₂-SnO₂ nanocrystalline- embedded amorphous electrode, grown by DC reactive sputtering, was investigated. X-ray diffraction (XRD), transmission electron microscopy (TEM), and transmission electron diffraction (TED) examination results showed that Sn and Ru metal cosputtered electrode in O₂/Ar ambient have RuO ₂-SnO₂ nanocrystallines in an amorphous oxide matrix. It is shown that the cyclic voltammorgram (CV) result of the RuO ₂-SnO₂ nanocrystalline-embedded amorphous film in 0.5 M H₂SO₄ liquid electrolyte is similar to a bulk-type supercapacitor behavior with a specific capacitance of 62.2 mF/cm² μm. This suggests that the RuO₂-SnO₂ nanocrystalline-embedded amorphous film can be employed in hybrid all-solid state energy storage devises as an electrode of supercapacitor.
