The First Semiconductor

The first semiconductor device is generally considered to be the point-contact diode, also known as the "cat's whisker" diode, invented by Jagadish Chandra Bose in 1899. This early semiconductor device was made using a semiconductor material (typically a mineral called galena) and a metal point contact. It allowed the flow of electric current in only one direction, making it a rudimentary rectifier.
