Description
The structure is cubic and has the fluorite arrangement.
The unit-cell parameters are: a = b= c = 4.5148 ?,
α= β = γ = 60°, cell volume = 65.07 ?
3.
Large high-purity single crystals of the semiconductor
Mg2Ge have been grown by a modified
Bridgman method. Crystals grown from stoichiometric
melts were p-type with carrier concentrations at 77 K of
about 10
16/cm
3 and Hall mobilities near 1100 cm
5/V s.
Excess magnesium placed in the melt acted as a donor
and produced n-type material.
Chemical Properties
cub crystal(s); used in semiconductor research [LID94] [MER06]
Uses
Magnesium germanide is used as primary and secondary intermediate and in chemical research. It forms germanium hydrides on exposure to hydrochloric acid.
Uses
In semiconductor research.
Structure and conformation
The space lattice of Mg
2Ge belongs to the cubic system, and it has an antifluorite type structure. In
the structure, Mg occupies the F
- position in CaF
2, and Ge occupies the Ca
2+ position.
