When doped with a material with an extra valence electron, it gives an overall negative charge. This is called an N-type semiconductor. When doped with a material that is short of one valence electron, it gives
Cell types are the basic functional units of an organism. Cell types exhibit diverse phenotypic properties at multiple levels, making them challenging to define, categorize, and understand. This review provides an overview of the basic principles of cell types rooted in evolution and development and...
Pure silicon is a semiconductor and does not conduct charge on its own. By adding impurities, or doping, the silicon becomes slightly charged and capable of conducting electricity. When the doping element has an extra valence electron it becomes a negatively chargedn-typeconductor. Common n-type ...
Atoms remain bound together by forces of attraction between an atom's nucleus and electrons in its outer shell. When influenced byvoltage, atoms in a circuit begin to reform and their components exert a potential of attraction known as a potential difference. Mutually attracted loose electrons move...
When we predict the shape of a molecule by reckoning up the number of electron pairs around the central atom, we should point out that this does not always give the right result (e.g. it fails for the SeCl62− and the TeCl62− ion, which have a regular octahedral structure). (...
