Issue Date: | 2022 | Publisher: | AMER PHYSICAL SOC | Source: | Physical Review Applied, 17 (2) (Art N° 024046) | Abstract: | With the advent of quantum technology, nitrogen vacancy (N -V) centers in diamond turn out to be a frontier that provides an efficient platform for quantum computation, communication, and sensing applications. Due to the coupled spin-charge dynamics of the N -V system, knowledge of N -V charge -state dynamics can help to formulate efficient spin-control sequences strategically. Here, we report two spectroscopy-based deconvolution methods to create charge-state mapping images of ensembles of N -V centers in diamond. First, relying on the fact that an off-axis external magnetic field mixes the electronic spins and selectively modifies the photoluminescence (PL) of N-V-, we perform decomposition of the optical spectrum for an ensemble of N -V and extract the spectra for N-V- and N -V0 states. Next, we introduce an optical-filter-based decomposition protocol and perform PL imaging for N-V- and N -V0. Previously obtained spectra for N-V- and N -V0 states are used to calculate their transmissivities through a long-pass optical filter. These results help us to determine the spatial distribution of the N -V charge states in a diamond sample. | Notes: | Chakraborty, T (corresponding author), Tech Univ Dortmund, Fak Phys, D-44221 Dortmund, Germany.; Chakraborty, T (corresponding author), Delft Univ Technol, QuTech & Kavli Inst Nanosci, NL-2600 GA Delft, Netherlands. t.chakraborty-1@tudelft.nl; Dieter.Suter@tu-dortmund.de; mahesh.ts@iiserpune.ac.in |
