Oleg Vladimirovich Losev (sometimes spelled Lossev or Lossew in English; Russian: Оле́г Влади́мирович Ло́сев; 10 May 1903 – 22 January 1942) was a Russian and Soviet scientist and inventor who made significant discoveries in the field of semiconductor junctions and the light emitting diode (LED).
Feb 11, 2011 · Learn about Oleg Losev, a self-taught Soviet engineer who discovered blue LEDs and negative resistance in zincite crystals. He built fully solid-state RF amplifiers, detectors and oscillators before transistors, but his work was largely unknown and lost during the Siege of Leningrad.
Mar 8, 2017 · Oleg Losev was a Russian engineer who created the first practical light-emitting diodes and semiconductor amplifiers in the 1920s, but his work was ignored and overshadowed by later discoveries. Learn about his life, achievements, and the challenges he faced in this article from Hackaday.
In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago and, independently, a forgotten Russian genius — Oleg Losev — discovered the LED.
A brilliant young Russian scientist, Oleg Losev, rediscovered the phenomenon in the 1920s. A technician with few formal qualifications, Losev worked independently on diodes with zinc ...
In a light-emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called "electroluminescence". The wavelength of the light depends on the energy band gap of the semiconductors used.
Oleg Losev (or Lossev) was a Russian scientist who made significant discoveries in the field of semiconductor junctions in the 1920s. He observed light emission from silicon carbide point-contact junctions, which was essentially the first light emitting diode (LED).
