FIG. 1.

(a) Pumped current normalized by vs the variation in the dc voltage applied to gate 2, . The inset shows a schematic of the device, with the dashed arrow indicating the direction of the pumped electrons. S and D indicate source and drain contacts. (b) in arbitrary units as a function of applied -field and . The number of electrons pumped per cycle is specified in the figure. The measurements were performed in device 1 at , base temperature of , and power of .

FIG. 2.

Pumped current at through device 2 as a function of and . In (a) no magnetic field was applied. The dotted line indicates the transition above which the emission of electrons to the drain is not complete and smaller than the number of loaded electrons . In (b) the pumped current is shown when a perpendicular-to-plane field of was applied.

FIG. 3.

Pumped current normalized by at through device 2 vs the variation in the dc voltage applied to gate 2, , at fixed . In (a) no field was applied, while (b) shows the characteristic for . The gate characteristic was fitted using Eq. (3) together with the following parameters: for zero field (a), , , while for the measurements at , (b) the values , , and were used.
