Kondo effect in nanostructures
arXiv:cond-mat/0512671 · doi:10.1002/pssa.200566191
Abstract
Kondo effect arises whenever a coupling to the Fermi gas induces transitions within the otherwise degenerate ground state multiplet of an interacting system. Both coupling to the Fermi gas and interactions are naturally present in any nanoscale transport experiment. At the same time, many nanostructures can easily be tuned to the vicinity of a degeneracy point. This is why the Kondo effect in its various forms often influences the low temperature transport in meso- and nanoscale systems. In this short review we discuss the basic physics of the Kondo effect and its manifestations in the low-temperature electronic transport through a single electron transistor.
