A capacitance standard based on the definition of capacitance C=Ne/U is realized if a capacitor is charged with a known number N of electrons (e is the elementary charge), and the voltage U across the capacitor is measured . If U is measured by means

The resistive anomaly, an increase of sample resistance above the normal state value at the top of the superconducting transition, has been studied experimentally in various aluminum nanostructures. The effect is not absolutely reproducible being dep

A nanostructure based on a uniform one-dimensional array of ultrasmall tunnel junctions (a single-electron trap) characterized by an ability to maintain an excess charge of several electrons in an island is fabricated and investigated. Changes in the

A single-electron trap built with two Superconductor (S) - Insulator (I) - Normal (N) metal tunnel junctions and coupled to a readout SINIS-type single-electron transistor A (SET A) was studied in a photon detection regime. As a source of photon irra

The hold time $\tau$ of a single-electron trap is shown to increase significantly due to suppression of environmentally assisted tunneling events. Using two rf-tight radiation shields instead of a single one, we demonstrate increase of $\tau$ by a fa

We fabricated and tested the single electron R-pump, i.e. a three-junction Al circuit with on-chip Cr resistors. We show that due to the presence of the resistors (R > h/e^2 = 25.8 kOhm), the accuracy of electron transfer in the R-pump can approach t

Pumping characteristics were studied of the hybrid normal-metal/superconductor single-electron transistor embedded in a high-ohmic environment. Two 3 micrometer-long microstrip resistors of CrOx with a sum resistance R=80kOhm were placed adjacent to

The dc transport properties of long arrays of small Al Josephson junctions, biased through on-chip Cr resistors, are studied. The IV-characteristics show a large Coulomb threshold for current as well as negative-slope regions indicating the regime of
