1. A method of preparing an amorphous sulfide exhibiting ionic conductivity, the method comprising:
preparing a metal or an alloy comprising the metal;
gas-phase supplying a sulfur source to a surface of the metal or the alloy; and
controlling a reaction rate by adjusting a reaction temperature between the sulfur source and the metal or the alloy in a range of about 20° C. to 300° C. and by adjusting a flow rate of the gas-phase supplying of the sulfur source to the surface of the metal or the alloy to control an interfacial distance between sulfur atoms of the sulfur source and atoms of the metal or the alloy, such that a density of the amorphous sulfide is adjusted,
wherein, as the reaction rate increases, the density of the amorphous sulfide decreases.
