← ScienceWhich risk increases when a voltage induces electron transition to higher orbitals in a transistor?
A)Increased gate oxide dielectric breakdown✓
B)Increased thermal conductivity of substrate
C)Reduced electromigration in metal interconnects
D)Increased quantum entanglement instability
💡 Explanation
Increasing the gate voltage leads to higher energy electron transitions involving the mechanism of dielectric polarization; because the electric field increases with voltage and orbital occupancy therefore risk of exceeding the gate oxide's dielectric strength arises, rather than thermal or electromigration risks.
