27. A variation in the addition energies is seen, but no clear four-electron shell structure is observed as is the case of device B. The origin of this difference is not understood except that the energy scales related to device B are much larger than in device A, making such effects more visible.
28. The Coulomb peaks measured at T=6.5K are already slightly suppressed by temperature.
