Paper Title:
High Energy Local Vibrational Modes of Carbon Aggregates in SiC: Experimental and Theoretical Insight
  Abstract

We observe new photoluminescence centers in electron-irradiated 6H-SiC with phonon replicas up to 250 meV and clear threefold isotope splitting of the highest energy mode. Based on ab initio calculations, we discuss the tri-carbon anti-site (C3)Si and the di-interstitial (C2)Hex as models for these centers.
