Statistical properties of electrochemical capacitance in disordered mesoscopic capacitors
Fuming Xu, Jian Wang
We numerically investigate the statistical properties of electrochemical capacitance in disordered two-dimensional mesoscopic capacitors. Based on the tight-binding Hamiltonian, th…
Transient dynamics of molecular devices under step-like pulse bias
Bin Wang, Yanxia Xing, Lei Zhang +1
We report first principles investigation of time-dependent current of molecular devices under a step-like pulse.Our results show that although the switch-on time of the molecular d…
Carbon nanotube-based quantum pump in the presence of superconducting lead
Yadong Wei, Jian Wang
Parametric electron pump through superconductor-carbon-nanotube based molecular devices was investigated. It is found that a dc current, which is assisted by resonant Andreev refle…
Parametric pumping at finite frequency
Baigeng Wang, Jian Wang, Hong Guo
We report on a first principles theory for analyzing the parametric electron pump at a finite frequency. The pump is controlled by two pumping parameters with phase difference .…
Resonant Andreev reflections in superconductor-carbon-nanotube devices
Yadong Wei, Jian Wang, Hong Guo +2
Resonant Andreev reflection through superconductor-carbon-nanotube devices was investigated theoretically with a focus on the superconducting proximity effect. Consistent with a re…
Nonlinear Quantum Capacitance
Baigeng Wang, Xuean Zhao, Jian Wang +1
We analyze the nonlinear voltage dependence of elelctrochemical capacitance for nano-scale conductors. This voltage dependence is due to finite density of states of the conductors.…
