Kondo Effect in a Single Electron Transistor Excited by Microwaves
M.A. Kastner, C.M. Marcus

(A) Evolution of the Kondo peak with increasing microwave voltage V_ds^osc applied to a single electron transistor SET at T = 100 mK.
(B) Separation between the satellites and the central peak as a function of the microwave voltage. The horizontal line is hf/e where h is Planck’s constant and f is the microwave frequency.
