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 …

We observe a strong Kondo effect in a semiconductor quantum dot when a small magnetic
field is applied. The Coulomb blockade for electron tunneling is overcome completely by the …

We report a strong Kondo effect (Kondo temperature∼ 4 K) at high magnetic field in a
selective area growth semiconductor quantum dot. The Kondo effect is ascribed to a singlet …

The Kondo effect—a many-body phenomenon in condensed-matter physics involving the
interaction between a localized spin and free electrons—was discovered in metals …

We investigate the Kondo effect in a quantum dot with almost degenerate spin-singlet and
triplet states for an even number of electrons. We show that the Kondo temperature as a …

We present measurements on the Kondo effect in a small quantum dot connected strongly to
one lead and weakly to the other. The conductance of the dot reveals an offset of the Kondo …

We study the nonequilibrium regime of the Kondo effect in a quantum dot laterally coupled to
a narrow wire. We observe a split Kondo resonance when a finite bias voltage is imposed …

The time development of the Kondo effect is theoretically investigated by studying a
quantum dot suddenly shifted into the Kondo regime by a change of voltage on a nearby …

We measured the phase evolution of electrons as they traverse a quantum dot (QD) formed
in a two-dimensional electron gas that serves as a localized spin. The traversal phase …

We show that the Kondo effect can be induced by an external magnetic field in quantum dots
with an even number of electrons. If the Zeeman energy B is close to the single-particle level …
