There Are Multiple Forms

PAM-XIAMEN offers Germanium wafer Single Crystals and Wafers grown by VGF / LEC, we have a strong advantage in providing Ge wafer for micro-electronics and opto-electronics industry in diameter range from 2 inch to 6 inch. Germanium wafer is an elemental and popular semiconductor material, due to its excellent crystallographic properties and unique electric properties, Germanium wafer is widely used in Sensor, Solar cell and Infrared optics applications. PAM-XIAMEN can provide low dislocation and epi ready Germanium wafers to meet your unique germanium requirement.

 

When it comes to germanium, there are five naturally occurring isotopes. They are germanium-70, germanium-72, germanium-73, germanium-74, and germanium-76. Isotopes are two or more forms of an element with each differing from each other according to their mass number. The mass number is the number located to the right of the element, which in this case is 70, 72, 73, 74, and 76. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. At least nine radioactive isotopes of germanium are also known.

 

Germanium Facts

  •  Germanium’s value was recognized during World War II when it was used in high-resolution radar receivers. The first germanium transistor was invented shortly afterward.
  •  Germanium is one of the few elements that expand when it freezes, just like water.
  •  The name “germanium” comes from the Latin name for Germany. Clemens Winkler, a German chemist, is believed to have found the first substrate of germanium in 1885.
  •  Germanium is commonly used in detectors in a variety of fields.
  •  Atomic Number: 32
  •  The existence of germanium was predicted by Russian chemist Dmitri Mendeleev in 1869 after he developed the periodic table of elements.
