Theoretical analysis of the experimental energy data for an electron tunneling into a single state and to two interacting electrons confined by finite Gaussian potential in two-dimensional quantum dot subjected uniform magnetic field perpendicular plane is presented. While previously published analytic solution at which 2-electron ground transitions from spin-singlet spin-triplet agreed well wi...

We show that, in the weak coupling limit, the main formalism of the phenomenological quantum I.angevin model for single electron tunneling in small tunnel junctions is derivable within the framework of the rigorous generalized Landauer formula. The study of Coulomb blockade, a suppression of single electron tunneling (SET) (for a review see Ref. [ 1 ] ) in small capacitance junctions, is attrac...

A system consisting of two independently contacted quantum dots with a strong electrostatic interaction shows an interdot Coulomb blockade when the dots are weakly tunnel coupled to their leads. How the blockade can be overcome by correlated tunneling when tunnel coupling to the leads increases is studied experimentally. The experimental results are compared with numerical renormalization group...
