Ripple Effect: Researchers say leveling of electrodeposits can be achieved by applying a small forcing voltage
Seeking smoother plating deposits? It may be all in the waves. This story looks at studies that have shown that superimposition of a small sinusoidal potential wave (smooth, repetitive oscillation) onto a potentiostatic bias can lead to more level e...
