← ScienceWhich outcome occurs regarding a Josephson junction's current when a small DC voltage is applied?
A)DC Josephson supercurrent flow occurs
B)AC Josephson oscillations begin✓
C)Quasiparticle tunneling is suppressed
D)Subharmonic gap structure disappears.
💡 Explanation
Applying a DC voltage generates AC Josephson oscillations because the **AC Josephson effect** dictates a frequency proportional to voltage; therefore, AC current oscillates rather than DC supercurrent, due to the applied voltage rather than the zero-voltage state.
