Let’s Begin…

The team at periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about gallium. Discover gallium and be amazed as you watch the experiment called "the beating heart".

Gallium’s most important modern application is in semiconductor crystals. Silicon semiconductors stop working at frequencies above a few gigahertz. However, gallium arsenide circuits can operate as high as 250 GHz, which is at the upper end of the microwave frequency range.
