Solid state rectifiers use semiconductor technology. This valuable technology has led to the term 1cSilicon Valley 1d and is commonly associated with the computer and transistor industries. The core material for semiconductors is silicon which is intentionally combined with impurities using the elements of arsenic, gallium and boron. This process is termed 1cdoping 1d and is used to control electron flow through an n-p interface or junction. How is arsenic used to affect semiconductor conductance?
What will be an ideal response?
Arsenic is an electron contributor through its single valence electron, which forms a covalent bond with silicon. This creates an electron charge carrier that is a better conductor of electron flow than gallium, which creates an electron 1chole 1d as a charge carrier. The doping of silicon with more and more arsenic improves is conductance across the n-p junction.
