To get a n type semiconductor from silicon
Webb10 juni 2024 · N-type Semiconductors Phosphorus has five valence electrons. Adding phosphorus to silicon rather than aluminum introduces an extra electron per impurity atom. The fifth valence electrons are not in low-energy covalent bonds but remain high-energy, just below the conduction band. Webb9 sep. 2024 · In this paper, we described a method of double-sided diffusion and drift of lithium-ions into monocrystalline silicon for the formation of the large-sized, p-i-n structured Si(Li) radiation detectors. The p-i-n structure is a p-n junction with a doped region, where the “i-region” is between the n and the p layers. A well-defined i-region is …
