Coulomb blockade in silicon based structures at temperatures up to 50 K

Observation of quantum effects and Coulomb blockade in silicon quantum-dot transistors at temperatures over 100 K

We report the fabrication and characterization of lithographically defined nanoscale silicon quantum-dot transistors that operate at temperatures over 100 K and a bias higher than 0.07 V. In the tunneling regime, these transistors show strong current oscillations due to quantum confinement and single-electron charging effects. In the propagating regime, a different kind of current modulation ha...

The Analysis of Coulomb Blockade in Fullerene Single Electron Transistor at Room Temperature

The Graphene based single electron transistor (SET) as a coulomb blockade device need to be explored .It is a unique device for high-speed operation in a nano scale regime. A single electron transfers via the coulomb barriers, but its movement may be prevented by coulomb blockade, so its effect is investigated in this research. The conditions of coulomb blockade and its controlling factors such...

Direct measurements of electron thermalization in Coulomb blockade nanothermometers at millikelvin temperatures

We investigate electron thermalization of tunnel junction arrays installed in a powerful dilution refrigerator whose mixing chamber can produce lattice temperatures down to 3mK. The on-chip Coulomb blockade thermometers (CBT) against other thermometers at the mixing chamber provide direct information on the thermal equilibrium between the electronic system and the refrigerator. We can detect an...

Room-temperature Coulomb-blockade-dominated transport in gold nanocluster structures

In this paper we discuss the near-room-temperature electrical transport characteristics of structures made from ligand-stabilized metal clusters. The structures show threshold behaviour, nonlinear current–voltage characteristics and radio-frequency-induced plateaux consistent with Coulomb-blockade-dominated transport in disordered arrays of metal dots. Samples having triphenylphosphine and octa...
