Magnesium germanide Usage And Synthesis

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 10¹⁶/cm³ and Hall mobilities near 1100 cm⁵/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 Mg₂Ge belongs to the cubic system, and it has an antifluorite type structure. In the structure, Mg occupies the F^- position in CaF₂, and Ge occupies the Ca²⁺ position.
