Abstract
The present disclosure relates to a method including, providing an apparatus that has an anode and a cathode, coupled to each other through a power supply and providing, in contact with the anode and the cathode, a liquid comprising a substrate and a material and providing 10 to 1000 nanosecond electric pulses between the cathode and the anode, wherein the material is electrodeposited onto a surface of the substrate, and wherein the substrate acts as either a cathode or an anode in the liquid. The electric pulses may be from 1 to 100,000 volts and for a period of 0.001 to 10,000 Hz. Also disclosed is a system for providing the electric pulses for electrodeposition onto a substrate.

A method comprising:
- providing an apparatus comprising an anode and a cathode, coupled to each other through a power supply;
- providing, in contact with the anode and the cathode, a liquid comprising a substrate and a material;
- and
- providing a series of electric pulses between the cathode and the anode with pulse durations in the range of 10 to 1000 nanoseconds, wherein the material is electrodeposited onto a surface of the substrate, wherein the substrate acts as either a cathode or an anode in the liquid.
A device comprising:
- an apparatus comprising an anode and a cathode, coupled to each other through a power supply;
- wherein the anode and the cathode contact a liquid comprising a substrate and a material;
- and wherein the power supply is configured to provide a series of electric pulses between the cathode and the anode with a pulse duration in the range of 10 to 1000 nanoseconds, such that the material is electrodeposited onto a surface of the substrate wherein the substrate contacts either a cathode or an anode in the liquid.
