Bose was the first to use a semiconductor junction to detect radio waves, and he invented various now-commonplace microwave components. In , Bose described to the Royal Institution in London his research carried out in Kolkata at millimetre wavelengths. Sir Nevill Mott , Nobel Laureate in for his own contributions to solid-state electronics, remarked that "J.
In fact, he had anticipated the existence of P-type and N-type semiconductors. His major contribution in the field of biophysics was the demonstration of the electrical nature of the conduction of various stimuli e. These claims were later proven experimentally. He researched the mechanism of the seasonal effect on plants, the effect of chemical inhibitors on plant stimuli and the effect of temperature.
Bose performed a comparative study of the fatigue response of various metals and organic tissue in plants. He subjected metals to a combination of mechanical, thermal, chemical, and electrical stimuli and noted the similarities between metals and cells. Bose's experiments demonstrated a cyclical fatigue response in both stimulated cells and metals, as well as a distinctive cyclical fatigue and recovery response across multiple types of stimuli in both living cells and metals.
Bose documented a characteristic electrical response curve of plant cells to electrical stimulus, as well as the decrease and eventual absence of this response in plants treated with anaesthetics or poison. The response was also absent in zinc treated with oxalic acid. He noted a similarity in reduction of elasticity between cooled metal wires and organic cells, as well as an impact on the recovery cycle period of the metal.
It was one of the first works of Bengali science fiction.
Bose's place in history has now been re-evaluated. His work may have contributed to the development of radio communication. Many of his instruments are still on display and remain largely usable now, over years later. They include various antennas, polarisers, and waveguides, which remain in use in modern forms today.
In the same year, India issued a postage stamp bearing his portrait. On 30 November , Bose was celebrated in a Google Doodle on the th anniversary of his birth. Indian scientist Sir Jagadish Chandra Bose has been featured in that nomination list for his pioneering work on Wifi technology.
