WebJun 4, 1998 · Two new experiments are presented which suggest that the ‘‘bulk‐compensating donor’’ phenomenon observed in p‐Si is probably a deactivation process of the boron acceptor by hydrogen with the formation of a B − H + pair. The two experiments are (i) avalanche hole injection in Al‐gate metal‐oxide‐silicon capacitor from … WebBoron is the most common p-type impurity in silicon, whereas arsenic and phosphorus are used extensively as n-type dopants. These three elements are highly soluble in silicon … WebSilicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. rollaway single beds

(Note: When discussing periodic table groups, semiconductor physicists always use an older notation, not the current IUPAC group notation. For example, the carbon group is called "Group IV", not "Group 14".) For the Group IV semiconductors such as diamond, silicon, germanium, silicon carbide, and silicon–germanium, the most common dopants are acceptors from Group III or donors from Group V http://www.cityu.edu.hk/phy/appkchu/AP6120/9.PDF
