Magnesium germanide

Magnesium germanide 化学特性,用途語,生産方法

• 説明

  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.

• 化学的特性

  cub crystal(s); used in semiconductor research [LID94] [MER06]

• 使用

  Magnesium germanide is used as primary and secondary intermediate and in chemical research. It forms germanium hydrides on exposure to hydrochloric acid.

• 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.
