Almost every chip we use is made of "silicon." But some of the heavy lifting — the high voltage in an EV inverter, fast charging, 5G signals, the lasers in an AI data center — is something silicon does poorly. For that you need a different family of crystals: compound semiconductors (silicon carbide SiC, gallium nitride GaN, gallium arsenide GaAs, indium phosphide InP). Here's the secret: the hardest, most valuable step isn't making the chip — it's growing the crystal in the first place. SiC has to be grown in a 2,500°C furnace for weeks just to yield an ingot a few centimeters long. This is the story of a tiny raw material that decides the whole game.
