A new study, “Spin-dependent optical activity of the telecom range ClV center in SiC: a wavefunction theory analysis”, provides important theoretical insights into the chlorine-vacancy (ClV) defect in silicon carbide (SiC) – an emerging quantum defect that operates in the telecom wavelength range. 🌐💡 Using advanced wavefunction-based theoretical methods, researchers working on the QRC-4-ESP project reveal how the ClV centre exhibits spin-dependent optical properties, deepen
