Simulations reveal the atomic-scale story of qubits
Investigated atomic pathways in 3C-SiC. a) Monovacancy dynamics, including carbon (VC) and silicon (VSi) vacancy migration, and VSi and carbon antisite vacancy complex (CAV) inter-conversion. b) Pairing of second (V-V2) and third (V-V3) neighbors VC and VSi vacancies to form a double vacancy VV. Only V-V up to third neighbors were considered, due to the size of our supercells. c) VV migration path with the lowest barrier, where steps 1 to 3 are illustrated. VCCSiVC complex in step 3 is denoted as VCV. Credit: Nature…
