A rare element, discovered in 1885 in a silver ore (argyrodite) at Freiberg. It is a brittle, silver-white metal, chemically intermediate between the metals and nonmetals, resembles tin, and is in general identical with the predicted ekasilicon. Symbol Ge. Atomic number 32. Atomic weight 72.59. It has excellent semiconductor properties, and is used in transistors and diodes.
A grayish-white metal having semiconductor properties.
A brittle, grayish-white metallic element having semiconductor properties. Widely used in crystal diodes and early transistors.

A common material used for optical elements such as lenses or windows in LWIR systems. While this material transmits in the LWIR region, it is opaque in the visible region, appearing black.
a brittle gray crystalline element that is a semiconducting metalloid (resembling silicon) used in transistors; occurs in germanite and argyrodite
A chemical element that acts as a semiconductor, meaning sometimes it conducts electricity and sometimes it doesn't. The first transistors were all made out of germanium.
A metallic element used in diodes and transistors for its semiconductor properties. Glass paper an abrasive paper used to smooth the rough edges of freshly sawn wood
atomic symbol, Ge, germanium is the 32nd element in the periodic table (atomic number 32) with an atomic weight of 77.60, germanium is a semiconductor with a energy gap of 0.66eV at 300oK. Germanium has higher electron and hole mobility than silicon buts it's relatively narrow energy gap makes it's high temperature performance poor. Silicon has replaced germanium in virtually all applications due to it's higher energy gap and relative ease of fabrication.
