← ScienceWhich mechanism limits leakage current in a tunnel diode at full reverse bias?
A)Decreased density of states alignment✓
B)Increased thermionic emission rate
C)Enhanced defect-assisted recombination
D)Reduced minority carrier injection
💡 Explanation
At full reverse bias, quantum tunneling is suppressed because the energy bands are misaligned, reducing the density of available states for electrons to tunnel through the potential barrier. Therefore, decreased density of states alignment limits leakage, rather than enhanced emission, recombination, or injection which are independent failure causes.
