Fig. 4From: Physical and electrochemical area determination of electrodeposited Ni, Co, and NiCo thin filmsExample double-layer capacitance measurements for a NiCo thin film. The sample had a deposited charge of 1000Â mC. The inset shows CV measurements in 1Â M KOH at 75, 225, and 350Â mV/s. The slope of the linear fit to the capacitive current, \(I_\mathrm {dl}\), vs. scan rate, v, is the measured double-layer capacitance, \(C_\mathrm {dl}\), for the sampleBack to article page
