Abstract

In 1955, it was first suggested that Hall effect can be employed for amplification purposes by using semiconductor material with very high mobility. While this idea was limited at that time, yet it was not entirely discarded expecting eventual progress. We revisit this idea and discuss it in the light of current literature. This manuscript kindles this 65 year old amazing idea and views it with modern understanding, which will aid in realizing Hall amplifiers.
