Ab-initio study of silicon carbide flakes and quantum dots

From density-functional theory calculations on two-dimensional SiC flakes and three-dimensional SiC quantum dots, the effects that single-point and two-point vacancy defects have on optical properties are studied. SiC flakes and SiC quantum dots of different sizes are considered and calculated properties are compared with existing first-principle studies on monolayer SiC. The application of these SiC nanostructes as possible candidate materials for quantum information technologies is discussed, specifically the research focuses on their promise as potential qubits or qudits to be used in spin-based quantum computing.
