China’s Silicon-Free Chip Breakthrough—The End of Moore’s Law?

Forget silicon, China just developed a transistor that’s faster and more efficient without it. If this works at scale, the entire semiconductor industry is about to be rewritten.
Peking University researchers claim they’ve outpaced Intel and TSMC’s best silicon chips with a bismuth-based 2D transistor, operating 40% faster while consuming 10% less energy.
The innovation eliminates silicon’s size limitations, using a gate-all-around field-effect transistor (GAAFET) to replace traditional chip structures:
- New materials allow faster, more efficient chips.
- China could sidestep US chip sanctions entirely.
- Manufacturing scale remains the biggest challenge.
This isn’t just an engineering feat, it’s a geopolitical shift. If China scales this tech, it could leapfrog the West’s semiconductor dominance. Can the industry adapt, or is it stuck in silicon-era thinking?
