• Germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of
the periodic table, a silvery-gray metalloid, intermediate in properties between
the metals and the nonmetals. Germanium did not become economically significant
until after 1945, when its properties as a semiconductor were recognized as being
of value in electronics. Many other substances now also are used as
semiconductors, but germanium remains of primary importance in the manufacture
of transistors and of components for devices such as rectifiers and photocells.
