Thermal Crossover between Ultrasmall Double and Single Junction
Heinz-Olaf Müller
The crossover from double-junction behavior to single-junction behavior of ultrasmall tunnel junctions is studied theoretically in a scanning-tunneling microscope setup. The indepe…
Electron Refrigeration in the Tunneling Approach
Heinz-Olaf Muller, K. A. Chao
The qualities of electron refrigeration by means of tunnel junctions between superconducting and normal--metal electrodes are studied theoretically. A suitable approximation of the…
Coulomb blockade threshold in inhomogeneous one-dimensional arrays of tunnel junctions
J. A. Melsen, Ulrik Hanke, H. -O. Müller +1
A general expression is given for the change in free energy when a charge tunnels through a junction in a one-dimensional array of N metallic islands with arbitrary capacitances an…
Ultrasmall double junction in terms of orthogonal polynomials
Heinz-Olaf Müller, Andreas Hädicke, Ulrik Hanke +1
The ``orthodox theory'' of a single electron double junction is dealt with. It is shown that the stationary solution of the underlying master equation allows the construction of an…
Elastic Co--Tunneling in a 1D Quantum Hole Approach
Heinz-Olaf Muller, Andreas Hadicke, Wolfram Krech
The influence of the phases of tunneling matrix elements on the rate of the elastic co--tunneling at an ultrasmall normal--conducting double--junction is studied in a simple quantu…
