Phys. Rev. Lett. 80, 5365–5368 (1998)Synthesis and Structure of Silicon-doped HeterofullerenesReceived 9 January 1998; published in the issue dated 15 June 1998 We report on the synthesis of C2n-qSiq clusters with 2n = 32-100 and q<4. The analysis of the abundance distribution and photofragmentation spectra provides clear evidences that such clusters remain in the fullerene geometry and that the Si atoms are located close to each other in the fullerene network. These results are corroborated by ab initio calculations within the density functional theory. The stability and electronic properties of these heterofullerenes are discussed. © 1998 The American Physical Society URL:
