Negative differential resistance due to the resonance coupling of a quantum-dot dimer
S. D. Wang, Z. Z. Sun, N. Cue +1
Electron tunneling through a coupled quantum-dot dimer under a dc-bias is investigated. We find that a peak in the - curve appears at low temperature when two discrete electr…

Limit cycle theory of temporal current self-oscillations in sequential tunneling of superlattices
X. R. Wang, Z. Z. Sun, S. Q. Duan +1
A unified theory of the temporal current self-oscillations is presented. We establish these oscillations as the manifestations of limit cycles, around unstable steady-state solutio…
