Brian Kidd Ridley

Brian Kidd Ridley (2 March 1931 – 22 May 2024) was a British solid-state physicist specialising in semiconductor theory. He was an emeritus professor at the University of Essex.

Early life and education Ridley was born on 2 March 1931. He educated at the University of Durham. He received a BSc degree in physics in 1953 and completed his doctoral studies in 1957.

Career Ridley began his career as a research physicist in the solid-state physics division of the Mullard Research Laboratories in Redhill, Surrey (1956–1964).

Research Ridley conducted work on negative differential resistance (NDR), instabilities and hot-electron transport in semiconductors. In the early 1960s, In 2001, the Institute of Physics awarded him the Dirac Medal in recognition of his four-decade long influence on the semiconductor theory.
