Hybridized Defects in Solid-State Materials as Artificial Molecules

نویسندگان

چکیده

Two-dimensional materials can be crafted with structural precision approaching the atomic scale, enabling quantum defects-by-design. These defects are frequently described as “artificial atoms” and emerging optically addressable spin qubits. However, interactions coupling of such artificial atoms each other, in presence lattice, warrants further investigation. Here we present formation molecules” solids, introducing a chemical degree freedom control optoelectronic materials. Specifically, monolayer hexagonal boron nitride our model system, observe configuration- distance-dependent dissociation curves hybridization defect orbitals within bandgap into bonding antibonding orbitals, splitting energies ranging from ?10 meV to nearly 1 eV. We calculate energetics cis trans out-of-plane pairs CHB–CHB against an in-plane pair CB–CB find that interacts more strongly than pairs. demonstrate application this by varying distance between CB VN CBVN changes predicted peak absorption wavelength visible near-infrared spectral band. envision leveraging complexes precisely tune properties toward engineering robust memories emitters for information science.
