An intrinsic (pure) semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. In intrinsic semiconductors the number of excited electrons and …

An extrinsic semiconductor which has been doped with electron donor atoms is called an n-type semiconductor, because the majority of charge carriers in the crystal are negative electrons. An electron acceptor dopant is an atom which accepts an electron from the lattice, creating a vacancy where an electron should be called a hole which can move ...

Un semiconductor (abreviadamente, SC) es un elemento que se comporta o bien como un conductor o bien como un aislante dependiendo de diversos factores, por ejemplo: el campo eléctrico o magnético, la presión, la radiación que le incide, o la temperatura del ambiente en el que se encuentre. [1] Los elementos químicos semiconductores de la tabla periódica se …
