Which 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.
