Episode notes
Silicon's Bandgap Limits High-Heat Use
- Silicon's narrow band gap lowers switching voltage but raises thermal leakage risks.
- Heat-driven leakage creates a feedback loop that limits transistor density and reliability.
Wide Bandgap Tradeoffs Matter
- Ultra-wide bandgap materials (SiC, GaN) offer higher voltage and thermal tolerance than silicon.
- Each material trades off mobility, stability, toxicity, and manufacturability for those advantages.
Diamond's Exceptional Physical Package
- Diamond combines ultra-wide band gap, very high breakdown field, and high carrier mobility in one material.
- Its thermal conductivity far exceeds silicon and copper, enabling much higher power densities.
