Electrically driven optical interferometry with spins in …
Here, we demonstrate electrically driven coherent quantum interference in the optical transition of single, basally oriented divacancies in commercially available 4H silicon carbide. By applying microwave frequency electric fields, we coherently drive the divacancy’s excited-state orbitals and induce Landau-Zener-Stückelberg interference fringes in the resonant optical absorption spectrum.
PICOSEC (Pico-second Silicon photomultiplier-Electronics- & Crystal research) is an European Marie Curie training project. It aims to bring together early career researchers and experienced colleagues from across Europe, to take part in a structured, integrated and multidisciplinary training program for young researchers in an R&D project geared to develop a new class of ultra-fast photon
Semiconductor Materials - IFM
Here we demonstrate that missing atoms in a silicon carbide crystal can host single spins that are accessible by optical spectroscopy, with long coherence times even at room temperature. These results expand the interest of silicon carbide into the areas of quantum processing and integrated spintronics.

Using first-principles methods we performed a theoretical study of carbon clusters in silicon carbide (SiC) nanowires. We examined small clusters with carbon interstitials and antisites in hydrogen-passivated SiC nanowires growth along the  and  directions. The formation energies of these clusters were calculated as a function of the carbon concentration. We verified that the

Abstract: The leakage currents through the gate oxide of MOS capacitors fabried on n-type 4H-Silicon Carbide (SiC) was measured under accumulation bias conditions with heavy-ion irradiation. The Linear Energy Transfer (LET) dependence of the critical electric field (E cr) at which dielectric breakdown occurred in these capacitors with two different oxide thicknesses was evaluated.
