Germanium
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.

Germanium
(n.)
A rare element, recently discovered (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 weight 72.3.

Germanium
Name: germanium
Symbol: Ge
Atomic number: 32
Atomic weight: 72.61 (2)
Group in periodic table: 14
Group name:
Period in periodic table: 4
Block in periodic table: p-block
CAS registry ID: 7440-56-4
The element is a gray-white metalloid, and in its pure state is crystalline and brittle, retaining its lustre in air at room temperature. It is a very important semiconductor material. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with an impurity of only one part in 10-10.
Certain germanium compounds have a low mammalian toxicity, but a clear activity against certain bacteria, which makes them of interest as chemotherapeutic agents.

Germanium
Germanium (IPA: ) is a chemical element in the periodic table that has the symbol Ge and atomic number 32. This is a lustrous, hard, silver-white metalloid that is chemically similar to tin. Germanium forms a large number of organometallic compounds and is an important semiconductor material used in transistors.
