    The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony.The triode, however, was a fragile device that consumed a substantial amount of power. In 1909, physicist William Eccles discovered the crystal diode oscillator. Austro-Hungarian physicist Julius Edgar Lilienfeld filed a patent for a field-effect transistor (FET) in Canada in
