Abstract
We fabricated and tested the single electron R-pump, i.e., a three-junction Al circuit with on-chip Cr resistors. Due to the presence of the resistors (R>R/sub K/=h/e/sup 2//spl ap/25.8 k/spl Omega/), the accuracy of electron transfer in the R-pump can approach the level of /spl delta/I/I/spl sim/10/sup -8/. Preliminary results of experiment with the R-pump made at PTB are reported.
