Kondo temperature dependence of the Kondo splitting in a single-electron transistor

Kondo temperature dependence of the Kondo splitting in a single-electron transistor

A Kondo peak in the differential conductance of a single-electron transistor is measured as a function of both the magnetic field and the Kondo temperature. We observe that the Kondo splitting decreases logarithmically with the Kondo temperature and that there exists a critical magnetic field ${B}_{\mathrm{C}}$ below which the Kondo …
