Description: In 1907 Captain Henry Joseph Round applied a voltage to a piece of silicon carbide (SiC), also know as Carborundum. He saw that it gave light. It is a phenomenon known as electroluminiscence and it was the first ancestor of the LED or Light Emitting Diode. en.wikipedia.org/wiki/Light-emitting_diode en.wikipedia.org/wiki/H._J._Round en.wikipedia.org/wiki/Silicon_carbide en.wikipedia.org/wiki/Semiconductor en.wikipedia.org/wiki/Diode en.wikipedia.org/wiki/Electroluminescence Susbcribe ► youtube.com/subscription_center?add_user=cienciabit Do you want to contribute subtitles? ► youtube.com/timedtext_cs_panel?tab=2&c=UCM7Dwmo0031iRaGdDunPaQw Cienciabit ► cienciabit.com Cherry Blossom - Wonders by Kevin MacLeod is licensed under a Creative Commons Attribution license (creativecommons.org/licenses/by/4.0/) Source: incompetech.com/music/royalty-free/index.html?isrc=USUAN1100382 Artist: incompetech.com
