چکیده
Optically active defects in solids with accessible spin states are promising candidates for solid state quantum information and sensing applications. To employ these as building blocks, coherent manipulation of their is required. Here we realize control ensembles boron vacancy (V$_B^-$) centers hexagonal nitride (hBN). Specifically, by applying pulsed resonance protocols, measure spin-lattice relaxation time ($T_1$) 18 $\mu$s coherence ($T_2$) 2 at room temperature. The increases three orders magnitude cryogenic Furthermore, employing a two- three-pulse electron spin-echo envelope modulation (ESEEM) separate the quadrupole hyperfine interactions surrounding nuclei. Finally, method to decouple from its inhomogeneous nuclear environment - "hole-burning" spectral optically detected magnetic linewidth significantly reduced several tens kHz, thus extending factor three. Our results important employment van der Waals materials technologies, specifically context using hBN high-resolution sensor hybrid systems including 2D heterostructures, nanoscale devices emerging atomically thin magnets.

متن کاملMetal-free spin and spin-gapless semiconducting heterobilayers: monolayer boron carbonitrides on hexagonal boron nitride.
The interfaces between monolayer boron carbonitrides and hexagonal boron nitride (h-BN) play an important role in their practical applications. Herein, we respectively investigate the structural and electronic properties of two metal-free heterobilayers constructed by vertically stacking two-dimensional (2D) spintronic materials (B4CN3 and B3CN4) on a h-BN monolayer from the viewpoints of latti...
متن کاملDefect-related photoluminescence of hexagonal boron nitride
Photoluminescence of polycrystalline hexagonal boron nitride (hBN) was measured by means of time-and energy-resolved spectroscopy methods. The observed bands are related to DAP transitions, impurities and structural defects. The excitation of samples by high-energy photons above 5.4 eV enables a phenomenon of photostimulated luminescence (PSL), which is due to distantly trapped CB electrons and...
