The invention of the diode can't be attributed to a single person, but rather to a series of developments over time. The basic idea of a diode is a component that allows current to flow in one direction and blocks it in the other.
The first type of diode was a vacuum tube diode, which was invented by John Ambrose Fleming in 1904. He created it as part of his work on detecting radio waves. The vacuum tube diode had two components: a cathode (which emitted electrons) and an anode (which collected them), allowing current to flow in one direction.
Later, the solid-state diode, which is much more common today, was developed with the discovery of semiconductors. In the 1940s, scientists like Julius Lilienfeld and Walter Schottky contributed to the understanding of semiconductor materials. However, the practical development of modern solid-state diodes is often credited to researchers at Bell Labs, particularly John Bardeen, Walter Brattain, and William Shockley, who created the first transistor in 1947. This work was key to the later development of modern semiconductor diodes.
So, while John Ambrose Fleming is credited with inventing the first vacuum tube diode, the evolution into modern diodes came from the advancements in semiconductor physics and the invention of the transistor.
