Einthoven Theory

Einthoven's theory of potential difference is a hypothesis from semiconductor physics, according to which a semiconductor diode will behave in the same way as a simple diode, but at high currents the diode will begin to behave unstable. This phenomenon was noticed by Peter Carl Van Eycknburg Einthoven (1860) on some carborundum crystals purchased by the Dutch company Philips, and reported about it in one of his patents dated July 21 (New Art.), 1910.
