  • Gallium - Wikipedia

    Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery blue metal at standard temperature and pressure; however in its liquid state it becomes silvery white.If too much force is applied Gallium may fracture conchoidally.It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium, and ...

    As a semiconductor, germanium allowed the production of a solid state equivalent to the diode. Like most semiconductors, germanium can have impurities added to make it an electron donor - a so-called n-type material - or an electron acceptor, called p-type. By marrying p and n type strips of germanium, the element provided the same diode effect.
