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…

The effect of inter-Landau-band mixing on extended states in quantum Hall system
Gang Xiong, Shi-Dong Wang, Qian Niu +4
The effect of inter-Landau-band mixing on electron localization in an integer quantum Hall system is studied. We find that mixing of localized states with {\it opposite chirality}…
