Claim:
1. A method of forming a nanostructure by electrochemical deposition, comprising: positioning a plurality of electrodes which includes a working electrode in a growth solution in an electrolytic deposition reactor; growing a first nanostructure on the working electrode by supplying a first applying power source between the plurality of electrodes for a first applying time and supplying oxygen/inert gas into the electrolytic deposition reactor; and growing a second nanostructure on the first nanostructure grown on the working electrode by supplying a second applying power source between the plurality of electrodes for a second applying time and supplying oxygen/inert gas into the electrolytic deposition reactor, wherein the first applying power source and the second applying power source are different from each other, wherein the first applying power source is in a range of −0.8 to −1.2 V and the first applying time is in a range of 6 to 240 seconds, wherein the second applying power source is in a range of −0.5 to −0.8 V and the second applying time is in a range of 900 to 1,500 seconds, and wherein the growing of the first nanostructure and the growing of the second nanostructure are performed at a temperature in a range of 80 to 100° C.
