Polytype Distribution in Circumstellar Silicon Carbide | …

The inferred crystallographic class of circumstellar silicon carbide based on astronomical infrared spectra is controversial. We have directly determined the polytype distribution of circumstellar SiC from transmission electron microscopy of presolar silicon carbide from the Murchison carbonaceous meteorite. Only two polytypes (of a possible several hundred) were observed: cubic 3C 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. In

In recent years, cubic silicon carbide (3C-SiC) has gained increasing interest as semiconductor material for energy saving and optoelectronic appliions, such as intermediate-band solar cells, photoelectrochemical water splitting, and quantum key distribution, just to name a few. All these appliions critically depend on further understanding of defect behavior at the atomic level and the

Silicon Carbide - Older than the stars

However the indiions are that the meteoritic silicon carbide data point to the presence of the cubic-β polymorph rather than the predominant α-hexagonal polymorph as found in laboratory experiments. Reasons for this anomaly are not clear (Kelly 2001).
