Million-Atom Pseudopotential Calculation of GX Mixing in GaAs AlAs
... The crossover from direct band gap to indirect band gap (e.g., G ! X) as a function of an external parameter is common in semiconductor physics. It is seen in (i) zinc blende materials (GaAs [1], InP [2]) as a function of pressure, (ii) alloys (Alx Ga12x As [3], Gax In12x P [4]) as a function of com ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
