Dawon Kahng (Korean: 강대원; May 4, 1931 – May 13, 1992) was a Korean-American electrical engineer and inventor, known for his work in solid-state electronics.

Kahng and Atalla later proposed the concept of the MOS integrated circuit, and they did pioneering work on Schottky diodes and nanolayer-base transistors in the early 1960s.

[3] He was a researcher at Bell Telephone Laboratories in Murray Hill, New Jersey, and he invented MOSFET (metal–oxide–semiconductor field-effect transistor), which is the basic element in most of today's electronic equipment, with Mohamed Atalla in 1959.

With its low resistance and short transit times in the thin metallic nanolayer base, the device was capable of high operation frequency compared to bipolar transistors.

He also conducted research on ferro-electric semiconductors and luminous materials, and made important contributions to the field of electroluminescence.

He was also a recipient of the Stuart Ballantine Medal of the Franklin Institute and the Distinguished Alumnus Award of the Ohio State University College of Engineering.
