A radio-frequency single-electron transistor (RF-SET), was used for the detection of single-electron tunneling through a quantum dot. Two electrically isolated SETs were integrated in an AlGaAs/GaAs heterostructure. Single-electron tunneling events were observed in both frequency and time domains. The results show that the accuracy of electron counting can be improved by increasing the coupling coefficient and decreasing the background noise in the measurement system.
