Digermane is a chemical compound selected from the group consisting of germane.

Production and representation

Digermane can be obtained by passing Mono German by silent electric discharge, while digermane and Trigerman formed as main products and next higher germane to Nonagerman. In other methods for preparing mono German emerge as the acid decomposition of Mg2Ge with ammonium bromide results in higher germane.

Properties

Digermane is a colorless gas, which decomposes upon heating.

Use

Digermane is used for deposition of amorphous germanium and the epitaxial thin films. It is used by means of epitaxy, the formation of boron -doped silicon -germanium alloy layer and with diborane in the formation of boron -doped germanium films.
