Late formation of silicon carbide in type II supernovae

We have found that individual presolar silicon carbide (SiC) dust grains from supernovae show a positive correlation between 49Ti and 28Si excesses, which is attributed to the radioactive decay of the short-lived ( t ½ = 330 days) 49V to 49Ti in the inner highly 28Si-rich Si/S zone. The 49V-49Ti chronometer shows that these supernova SiC dust grains formed at least 2 years after their parent

How are n-type and p-type materials prepared? - Quora

Since only 4 electrons are shared, the electron is not really needed where it''s atom is. The electron can find it relatively easy to move around the crystal. These forms a "free electron" and a "n-type" material. A few things to note: It only takes 1 out of a 1,000,000 or so atoms to be replaced to form a p-type or n-type …
