Title: Form of silicon and method of making the same

Abstract

The invention relates to a new phase of silicon, Si.sub.24, and a method of making the same. Si.sub.24 has a quasi-direct band gap, with a direct gap value of 1.34 eV and an indirect gap value of 1.3 eV. The invention also relates to a compound of the formula Na.sub.4Si.sub.24 and a method of making the same. Na.sub.4Si.sub.24 may be used as a precursor to make Si.sub.24.
