Abstract
According to example embodiments, a metallic glass includes aluminum (Al), a first element group, and a second element group. The first element group includes at least one of a transition metal and a rare earth element. The second element group includes at least one of an alkaline metal, an alkaline-earth metal, a semi-metal, and a non-metal. The second element group and aluminum have an electronegativity difference of greater than or equal to about 0.25. The second element group is included less than or equal to about 3 at % of the metallic glass, based on the total amount of the aluminum (Al), the first element group, and the second element group. A conductive paste and/or an electrode of an electronic device may be formed using the metallic glass.
