Abstract(in English) Single-electron transistor (SET) is the expected future integrated device with very low power consumption in operation and high functionality. For realistic device application, with a view to the room-temperature operation it is important to achieve nanodots less than 10 nm in size and stable characteristics. Here we used single-layer granular thin films in which Fe-nanodot arrays are dispersed in a MgF2 insulating matrix as a candidate structure for small-size metal nanodots. The SETs were fabricated by depositing the granular thin film between nano-gap electrodes and their electrical characteristics were investigated between 7 K and 300 K. We observed Coulomb oscillations even at 210 K. Furthermore, the offset charge drift, which is the time-dependent phase shift of Coulomb oscillations of the SET, was much smaller than that of a metal-based SET with an Al single-electron island and Al2O3 tunnel junctions. The results clearly indicate a high time stability of the Coulomb oscillations.
