Abstract
Hexagonal boron nitride (h-BN), a wide bandgap, two-dimensional solid-state
material, hosts pure single-photon emitters that have shown signatures of
optically-addressable electronic spins. Here, we report on a single emitter in
h-BN exhibiting optically detected magnetic resonance at room temperature, and
we propose a model for its electronic structure and optical dynamics. Using
photon emission correlation spectroscopy in conjunction with time-domain
optical and microwave experiments, we establish key features of the emitter's
electronic structure. Specifically, we propose a model that includes a spinless
optical ground and excited state, a metastable spin-1/2 configuration, and an
emission modulation mechanism. Using optical and spin dynamics simulations, we
constrain and quantify transition rates in the model, and we design protocols
that optimize the signal-to-noise ratio for spin readout. This constitutes a
necessary step toward quantum control of spin states in h-BN.
