Fig. 5: Spectral densities of electron–phonon coupling for basal divacancies.
From: Theory of the divacancy in 4H-SiC: impact of Jahn-Teller effect on optical properties

a Spectral function S(ℏω) of the \({3\atop}{A}^{{\prime} }{\to}{3\atop}{A}^{{\prime} }\) and b\({3\atop}{A}^{{\prime} }{\to}{3\atop}{A}^{{\prime} }\) optical transitions for hk divacancy. c Spectral function S(ℏω) of the 3A → 3A and d3A″ → 3A″ optical transitions for kh divacancy. Results are for the (23 × 23 × 7) supercell with 29,622 atomic sites.
