Germanium(IV) iodide (GeI4), not to be confused with germanium(II) iodide (GeI2), is an orange-red solid powder in its pure form, with a crystalline structure. Also known as germanium tetraiodide, this material is produced by heating germanium chloride with potassium iodide, or by introducing iodine vapor to heated elemental germanium.
Applications
Germanium iodide has few major commercial applications, though it is a target of research for its optical and electrical properties like other underutilized germanium crystal compounds.
Semiconductors. While not widely used like other germanium compounds, germanium tetraiodide may be of value in producing specialized semiconductors, or in the creation of germanium compounds of value as semiconducting materials. In particular, research has focused on germanium iodide as a perovskite material, with several researches investigating its potential in solar technology and other fields.
Nanoparticle research. Like many germanium compounds, nanoscience researchers have given special attention to the potential of high purity germanium iodide at nanoparticle scales.
