Description

Today were looking at silicon, and how introducing small amounts of other elements allow silicon layers to conduct currents, turning them into semiconductors. Well explore how putting two different types N and P semiconductors together gives us electrical components like diodes, transistors, and solar cells.

Crash Course Engineering is produced in association with PBS Digital Studios: https://www.youtube.com/playlist?list=PL1mtdjDVOoOqJzeaJAV15Tq0tZ1vKj7ZV
