24 Jul 1998 | Journal: | Science, 281 (5376), 540-4 | Abstract: | A tunable Kondo effect has been realized in small quantum dots. A dot can be switched from a Kondo system to a non-Kondo system as the number of electrons on the dot is changed from odd to even. The Kondo temperature can be tuned by means of a gate voltage as a single-particle energy state nears the Fermi energy. Measurements of the temperature and magnetic field dependence of a Coulomb-blockaded dot show good agreement with predictions of both equilibrium and nonequilibrium Kondo effects. | Source: | PubMed, pmid9677192 | Other source: | [GID 201783] cond-mat/9804211 | Services: | Forum | Review | Favorites |
