Observation of ionic Coulomb blockade in nanopores.
Emergent behaviour from electron-transport properties is routinely observed in systems with dimensions approaching the nanoscale. However, analogous mesoscopic behaviour resulting from ionic transport has so far not been observed, most probably because of bottlenecks in the controlled fabrication of subnanometre nanopores for use in nanofluidics. Here, we report measurements of ionic transport ...
متن کاملIonic Coulomb Blockade and Resonant Conduction in Biological Ion Channels
The conduction and selectivity of calcium/sodium ion channels are described in terms of ionic Coulomb blockade, a phenomenon based on charge discreteness and an electrostatic model of an ion channel. This novel approach provides a unified explanation of numerous observed and modelled conductance and selectivity phenomena, including the anomalous mole fraction effect and discrete conduction band...
متن کاملCoulomb blockade in Quantum Dots
In the resonant tunnelling diode we have treated electrons as non interacting particles. We have discussed their wave nature, which led to quantized energy states in small and coherent cavities. Qualitatively this is due to the requirement that an integer number of Fermi wavelengths has to fit between the barriers. Here we begin in the opposite limit by neglecting space quantization effects in ...
متن کاملQuantum Effects in Coulomb Blockade
We review the quantum interference effects in a system of interacting electrons confined to a quantum dot. The review starts with a description of an isolated quantum dot. We discuss the Random Matrix theory (RMT) of the one-electron states in the dot, present the universal form of the interaction Hamiltonian compatible with the RMT, and derive the leading corrections to the universal interacti...
متن کاملIonic Coulomb blockade and anomalous mole fraction effect in NaChBac bacterial ion channels
We report an experimental study of the influences of the fixed charge and bulk ionic concentrations on the conduction of biological ion channels, and we consider the results within the framework of the ionic Coulomb blockade model of permeation and selectivity. Voltage clamp recordings were used to investigate the Na/Ca anomalous mole fraction effect (AMFE) exhibited by the bacterial sodium cha...
