The spin state of the neutral silicon vacancy in 3C-SiC

Recent theoretical studies show that the neutral silicon vacancy (V Si) in cubic silicon carbide (3C-SiC) exhibits negligible Jahn-Teller distortion.This provides an opportunity to study the energy sequence of different multiplets in a vacancy with genuine T d symmetry. Calculations using the local spin density approximation give a spin triplet as ground state.
