The first attempts to introduce carbon into glass date back to 1951. But up until recently, the use of carbon or carbide raw materials, and the oxidation, volatilization and decomposition that accompany high temperature melting, have limited the synthesis of true silicon oxycarbide glasses. Here, the term silicon-oxycarbide refers specifically to a carbon-containing silie glass wherein

Silicon carbide is a semiconductor containing silicon and carbon that can switch high current with lower losses, compared to a standard semiconductor. By incorporating Cree’s silicon carbide semiconductors into its product portfolio, ABB accelerates its entry into the fast-expanding EV sector.
Growth morphology analysis of silicon carbide thin film Thin film quality very much depends on various deposition parameters as well as the substrate preparation. Growth defects, impurities and non stoichiometric phases can inhibit smooth film growth.
With careful tuning of an external magnetic field, this polarization flows into the nearby nuclear spin. (Left) The crystal structure of silicon carbide (silicon in gold, carbon in silver) supports different types of defects, called color centers. The one shown here
6/8/2020· Boron carbide (B 4 C) has higher hardness than alumina or silicon carbide. Its oxidation product (B 2 O 3 ) provides a protective skin at high temperatures (> 800 o C). Because of its high hardness and wear resistance, boron carbide is applied in low-temperature appliions such as grinding wheel dressers, and abrasive blast or water jet nozzles.
Electronic properties of 3C silicon carbide with substitutional transition metal impurities are calculated using an ab initio full-potential linearized augmented plane wave technique. It is shown that transition metal atoms in an SiC host may exist in both magnetic and nonmagnetic states. For different impurity species, the transition from the nonmagnetic to the magnetic state and the
The magneto-spectroscopy studies of luminescence related to silicon-vacancy, in high quality 6H-SiC crystals grown by the seeded physical vapor transport method, are presented. The superior optical quality of these crystals allowed us to resolve a doublet structure of the 1.398 eV emission line (V_2 line), commonly assigned to the transitions involving two singlet states of the silicon-vacancy.
Imperfections of crystal structure, especially edge disloions of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its appliions. Using silicon carbide as an example, physicists from Cracow and Warsaw have shown that even such computationally demanding defects can be successfully examined with atomic accuracy by means of a
We demonstrated optically detected magnetic resonance (ODMR) measurements using three-dimensional (3D) arrayed silicon vacancies (VSis) in in-plane SiC pn diodes. Proton beam writing successfully created 3D arrayed VSis using different ion (proton

13/7/2020· Silicon carbide (SiC) has become a key player in the realization of scalable quantum technologies due to its ability to host optically addressable spin qubits and wafer-size samples. Here, we have demonstrated optically detected magnetic resonance (ODMR) with resonant excitation and clearly identified the ground state energy levels of the NV centers in 4H-SiC. Coherent manipulation of NV
