Events
1897 - J. J. Thomson discovered the electron.
(Nobel Media, 2017)1904 - John Ambrose Fleming invents the first
thermionic device. (The Open University, 2017)1939 - World War II begins (HistoryNet, 2017)1945 - World War II ends (HistoryNet, 2017)1782 - Alessandro Volta first used the word
"semiconducting" (Bellis, 2017)1833 - Michael Faraday first observed a
semiconductor effect in silver sulfide - as
temperature decreases the electrical resistance
of the semiconductor also decreases. (Bellis,
2017)1874 - Karl Braun observed the first
semiconductor diode effect. (Bellis, 2017)1906 - Ferdinand Braun invents the crystal
detector(otherwise known as the cat's whisker
detector) - the first solid state device. (Bellis,
