Walter Schottky Facts
Walter Hermann Schottky (July 23, 1886 to March 4, 1976) was a German physicist. He is credited with the invention of the screen-grid vacuum tube. He was the co-inventor of the ribbon loudspeaker.
Interesting Walter Schottky Facts:
Walter Schottky was born in Zurich, Switzerland, while his father, Friedrich Hermann Schottky, was professor of mathematics at the University of Zurich.
In 1892 the family moved to Germany when his father was posted to the University of Marburg.
Walter Schottky graduated from the Steglitz Gymnasium.
In 1908 he earned a B.S. in physics at the University of Berlin.
In 1912 he received his PhD in physics from Humboldt University with a thesis titled was Zur relativtheoretischen Energetik und Dynamik.
Max Planck and Heinrich Rubens were his teachers at Humboldt University.
From 1912 to 1914 he studied at the University of Jena.
In 1918 he patented a superheterodyne.
From 1919 to 1923 he was a lecturer at the University of Wurzburg.
He was a professor of theoretical physics at the University of Rostock from 1923 to 1927.
In 1924 Schottky and Erwin Gerlach invented the ribbon microphone.
They discovered that a fine ribbon could generate electric signals when suspended in a magnetic field.
Schottky's most important contribution was his discovery of the formula which computes the energy between a point charge and a flat metal surface.
Several electrical conductor effects are named for Schottky including the Schottky emission, the Schottky effect and the Schottky-Nordheim barrier.
Certain metal-semiconductor junctions are known a Schottky contact.
In 1936 he received the Hughes Medal for his discovery of spontaneous current variations in high-vacuum discharge tubes.
In 1964 he received the Werner von Siemens Ring for his scientific works.
