Irreversible formation of a network of linear defects has been observed for images showing recoination luminescence from injection diodes in hexagonal silicon carbide. The defects are related to disloions that are initially formed as a result of thermal stress near the tip of the contact probe and subsequently propagate through the diode area. The disloion network appears in the images

Silicon carbide can host point defects in the crystal lattice known as color centers. These defects can produce single photons on demand and thus serve as a platform for single-photon source. Such device is a fundamental resource for many emerging appli ion s of the quantum informat ion science.
Growth of graphene on silicon carbide is promising for large-scale device-ready production. A significant parameter characterizing the quality of the grown material is the nuer of layers. Here we report a simple, handy and affordable optical approach for precise nuer-of-layers determination of graphene based on the reflected power of a laser beam.
