Field-effect Transistor - History

History

The field-effect transistor was first patented by Julius Edgar Lilienfeld in 1925 and by Oskar Heil in 1934, but practical semi-conducting devices (the JFET) were only developed much later after the transistor effect was observed and explained by the team of William Shockley at Bell Labs in 1947. The MOSFET, which largely superseded the JFET and had a more profound effect on electronic development, was first proposed by Dawon Kahng in 1960.

Famous quotes containing the word history:

    Every member of the family of the future will be a producer of some kind and in some degree. The only one who will have the right of exemption will be the mother ...
    Ruth C. D. Havens, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 13, by Susan B. Anthony and Ida Husted Harper (1902)

    They are a sort of post-house,where the Fates
    Change horses, making history change its tune,
    Then spur away o’er empires and o’er states,
    Leaving at last not much besides chronology,
    Excepting the post-obits of theology.
    George Gordon Noel Byron (1788–1824)

    These anyway might think it was important
    That human history should not be shortened.
    Robert Frost (1874–1963)
