Description: (Physicist, Inventor)
Oleg Vladimirovich Losev was a renowned Russian and Soviet scientist and inventor who made significant contributions to the field of semiconductor junctions and the development of light emitting diodes (LEDs). Despite his lack of formal education and a research position, Losev conducted groundbreaking research on semiconductors, publishing numerous papers and securing patents for his discoveries. He observed light emission from carborundum point-contact junctions, proposed the first accurate theory of LED operation, and applied them in practical applications such as electroluminescence. Losev also delved into negative resistance in semiconductor junctions, leading to the creation of the first solid-state amplifiers, electronic oscillators, and superheterodyne radio receivers well before the invention of the transistor. While his accomplishments were initially overlooked, they were eventually acknowledged in the late 20th and early 21st centuries.
