Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

Atanu Patra, Paul Konrad, Andreas Sperlich +6

Negatively charged boron vacancies (${\mathrm{V}}_{\mathrm{B}}^{-}$) in hexagonal boron nitride (hBN) are emerging as promising solid-state spin qubits due to their optical accessibility, structu…
