Silicon Carbide and Epitaxial Graphene: Light/Matter Interfaces
Projects
Funding source: Deutsche Forschungsgemeinschaft (DFG)
Project leader: Heiko B. Weber
The proposal targets the simultaneous electrical and optical characterization of colour centers, in particular intrinsic defects, in Silicon carbide (SiC). For their targeted generation we develop a methodology that combines ion implantation and optimized annealing such that smallest defect concentrations underneath the SiC (0001) surface can be reached with the ultimate goal of access to single defects. The (0001) surface will be equipped with epitaxially grown electrodes, such that a space charge…

Individual point defects in solids are stable quantum systems often providing coherent electron spins and stable emission of single photons. Point defects in silicon carbide combine these advantages with a technologically mature semiconductor material platform. However, the solid-state environment leads to significant spreads in the transition frequencies of individual defects which mostly hinders observing cooperative effects. In this project, we address this challenge theoretically as well as…
