Charge sensitivity of superconducting single-electron transistor
It is shown that the noise-limited charge sensitivity of a single-electron transistor using superconductors (of either SISIS or NISIN type) operating near the threshold of quasiparticle tunneling, can be considerably higher than that of a similar transistor made of normal metals or semiconductors. The reason is that the superconducting energy gap, in contrast to the Coulomb blockade, is not sme...

متن کاملQuantum measurement characteristics of a double-dot single electron transistor
Owing to a few unique advantages, the double-dot single electron transistor has been proposed as an alternative detector for charge states. In this work, we present a further study for its signal-to-noise property, based on a full analysis of the setup configuration symmetry. It is found that the effectiveness of the double-dot detector can approach that of an ideal detector, if the symmetric c...
متن کاملDouble quantum dot Si single-electron transistor with multiple gate electrodes fabricated by PADOX
Double quantum dots (DQDs) are well known as devices for quantum information processing. For this usage, it is important to control the capacitive coupling between the two quantum dots. We have fabricated a DQD Si single-electron transistor (DQD SiSET) with multiple gate electrodes and clarified the fact that the capacitive coupling of the Si-DQDs is tunable by controlling the number of electro...
متن کاملStacked quantum dot transistor and charge- induced confinement enhancement
As the size of a transistor continuously scales down, single electron effects become important [1 – 3]. Previously, we have studied charge transport in single-electron quantum dot transistors which have a channel consisting of a silicon dot separated from the source and the drain by two constrictions [4], and in single-electron MOS memories that have a polysilicon dot floating gate stacked on a...
