A silicon wafer for microchip fabriion needs to be in single crystalline shape. This is only possible by using the two mentioned techniques which deliver a round wafer. Even if it is possible to cut the round single crystal into rectangular shape afterwards (e. g. by sawing) the round wafers have several advantages over an angular shape.

Superconductivity in heavily boron-doped silicon carbide
28/1/2009· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) . One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.

The deposition of the hydrogenated microcrystalline silicon carbide (μc-SiC:H) layers was carried out in a conventional rf (13.56 MHz) capacitive type plasma enhanced chemical vapour deposition (PECVD) system at a substrate temperature of 200 C from the mixture of silane, methane and argon at flow rates of 1.5 sccm, 1.5 sccm and 97 sccm respectively, with rf power density of 80 mW/cm 3 and
Vanadium spin qubits as telecom quantum emitters in …
Solid-state quantum emitters with spin registers are promising platforms for quantum communiion, yet few emit in the narrow telecom band necessary for low-loss fiber networks. Here, we create and isolate near-surface single vanadium dopants in silicon carbide (SiC) with stable and narrow emission in the O band, with brightness allowing cavity-free detection in a wafer-scale material.
