Abstract
We fabricated and tested a single electron transistor (SET) and we succeeded in operating it between 0.3 K and 1.4 K The SET island and the tunnel junctions electrodes are made by Al, while the tunnel insulating layer is AlOx. The SET is in the superconducting state because at the operating temperature the Al becomes superconducting. The two junctions are dc current biased at I-b and the voltage across them, V-DS changes periodically (with a period equal to the charge quantum e) by changing the gate voltage V-GFile in questo prodotto:
