Investigation of electrochemical properties of RuO2 thin films modified by e-beam irradiation

Cyclic voltammetry was employed to evaluate the electrochemical properties of the synthesized RuO2 films in terms of their application as electrodes of electrochemical capacitors. RuO2 irradiated with 40 kGy showed 2.7 times higher capacitance (520 Fg−1) than the as-electrodeposited sample (190 Fg−1).
