Single nuclear spin detection and control in a van der Waals material

Sample preparation

The hBN thin flakes were tape-exfoliated from a monocrystalline hBN crystal and transferred onto Si/SiO₂ substrates. Then we irradiated the hBN flakes with 2.5 keV ¹³CO₂ (99.0% ¹³C, Sigma-Aldrich) ions with a dose density of…
