Abstract
A method of preparing a silicon nanowire and a method of fabricating a lithium secondary battery including the silicon nanowire are provided. The method of preparing a silicon nanowire may include forming a catalyst layer including metal particles separated from one another on a silicon layer, selectively etching the silicon layer contacting the metal particles, and removing the metal particles.
