Analysis of heavily boron-doped diamond Raman spectrum [PDF]

Diamond and Related Materials, 2018
Abstract Lattice disorder, electronic Raman scattering, and Fano interaction effects are at the genesis of the Raman spectrum of heavily boron-doped diamond. However, no accurate unified description of this spectrum has been reported yet. In this work, we propose a novel analysis of the Raman spectrum of boron-doped diamond based on classical models ...
