He was born in Madison, Wisconsin, USA on. His elder brother William, his wife Jane and his colleague Walter Brattain helped him in communication as he used to be quieter and reserved. ![]() He was known as brilliant, quiet, generous, visionary, thoughtful and remarkable among his friends. Therefore, we pay tribute to John Bardeen, a genius Physicist and inventor. January is the month in which John Bardeen, one of the inventors of the transistor passed away (30 January 1991). įigure 1.John Bardeen receiving Physics Nobel prize in 1956. According to the diagram when current I 1 passes through the input circuit, it generates holes in a p-type inversion layer, and it modulates current I 2. 3 schematically illustrates the working of the point contact transistor. A gold strip is wrapped around polystyrene wedge which is pressed to the germanium slab. 2 shows the first point contact transistor at the Bell laboratories. ![]() 1 shows John Bardeen receiving the Nobel Prize in 1956. John Bardeen along with William Bradford Shockley and Walter Houser Brattain was awarded Nobel prize in Physics on 10 th December 1956 for their “investigations on semi-conductors and the discovery of the transistor effect”. Being invented in 1947 as a point contact transistor, it has now become an integral constituent of modern semiconductor industry with global estimated sales 477.9 billion US dollars in 2018. Once of most remarkable scientific inventions that has influenced our daily lives as well technological developments all over the world is the “transistor”.
