Abstract :
The single electron transistor (SET) is a key element in single electronics where device operation is based on one-by-one electron manipulation utilizing the Coulomb blockade effect. However, SET operation has so far been limited to below 4 K because even the smallest capacitance C of the SET has been about 100 aF. This means the requirement of charging energy e/sup 2/(2C) being much larger than the thermal energy could only be met at very low temperatures. We report here a Si-SET whose capacitance is only about 2 aF. Owing to this small capacitance, the Si-SET shows conductance oscillation even at room temperature.<>
