← ScienceWhich outcome arises when bias stimulates resonant tunneling?
A)Sharp current increase occurs suddenly✓
B)Device exhibits high electrical resistance
C)Thermal runaway leads to destruction
D)Capacitance becomes negligibly small
💡 Explanation
A sharp current increase occurs because voltage matches quantum well energy levels to electrode states. The resonant tunneling mechanism allows electrons to tunnel through potential barriers more readily; therefore current peaks sharply, rather than a high resistance state predominating.
