Hints for neutrino-process boron in presolar silicon …

We have studied more than 1000 presolar silicon carbide (SiC) grains from the Murchison CM2 chondrite for C- and Si-isotopic compositions. Twelve SiC X grains, characterized by strong enrichments in 28 Si and believed to originate from Type II Supernovae (SNeII), were also measured for Li- and B-isotopic compositions.

Boron Carbide - an overview | ScienceDirect Topics

Unlike boron carbide, silicon carbide is basically a line compound with essentially no range of stoichiometry. There are many polytypes of silicon carbide. These structures can be easily visualized by recognizing that they are all built up of hexagonal double layers where the double layer consists of a layer of silicon atoms in a hexagonal pattern over a layer of carbon atoms in a hexagonal layer.

Silicon - Uses | Britannica

Silicon - Silicon - Uses: Silicon’s atomic structure makes it an extremely important semiconductor (see crystal: Electric properties). Addition of an element such as boron, an atom of which can be substituted for a silicon atom in the crystal structure but which provides one less valence electron (boron is an acceptor atom) than silicon, allows silicon atoms to lose electrons to it.
