    Could somebody please tell me how long Gallium Arsendie devices have been around.

    I've got some study notes and am now wondering just how old they are. Information is as they state "no devices are currently made with Gallium Arsenide at the moment"

    Thanks guys-JDR04:confused:

    Hello,

    The wiki article states that GaAs microprocessors where made since 1980.
    http://en.wikipedia.org/wiki/Gallium_arsenide
    You may assume that it has been around before that time.
    Here I have found a PDF with info on the use of gallium:
    minerals.usgs.gov/minerals/pubs/commodity/gallium/460798.pdf

    in there is stated:
