TLS International: Evolution of LEDs

Applying 10 volts to a silicon carbide crystal, he noticed it emitted a very faint yellow glow. However, in 1927, the Russian inventor Oleg Losev became the first person to properly study LEDs. Losev’s research paper was distributed around Europe, and while many different people studied the phenomena, no real progress was made until decades later.

2020/8/8· On August 20, 1906, he filed a U.S. patent on "Means for receiving intelligent communiion by electric waves" for a silicon point-contact detector; it was awarded that Noveer. With two associates, Pickard founded the Wireless Specialty Apparatus Company to market "''s-whisker" crystal radio detectors; it was probably the first company to make and sell silicon semiconductor devices.

Who Invented the LED? - Inmesol News

Losev noticed something that Henry Joseph Round had previously observed: that the semiconductors used in radio receivers emitted light when an electric current passed through them. He then built a crystal diode with zinc oxide and silicon carbide which, as he had imagined,emitted photonswhen a current was passed through it.

Silicon carbide of this type was typically only used in the dawn of the LED industry due to it''s dim light output. The most noteworthy thing about the KL101 however is not its chemistry but its packaging; unlike most early Soviet LEDs which were packaged in robust metal can enclosures, the KL101 is merely a cube of SiC material pressed between two wires and drizzled with epoxy.
