The Graphene based single electron transistor (SET) as a coulomb blockade device need to be explored .It is a unique device for high-speed operation in a nano scale regime. A single electron transfers via the coulomb barriers, but its movement may be prevented by coulomb blockade, so its effect is investigated in this research. The conditions of coulomb blockade and its controlling factors such...

An automated single-slide staining device is described. Smears gram stained by the automatic device were equal in quality to the manual method.

In this paper, we have investigated the effects of asymmetry in the source and drain capacitance of metallic island single electron transistors. By comparing the source and drain Fermi levels, in the ground and source referenced biasing configurations, with the island’s discrete charging energy levels for various gate voltages, we have derived a set of closed form equations for the device thres...

Abstract Fiber components form the standard not only in modern telecommunication but also for future quantum information technology. For high-performance single-photon detection, superconducting nanowire detectors (SPDs) are typically fabricated on a silicon chip and fiber-coupled easy handling usage. The fiber-to-chip interface hinders SPD from being an all-fiber device full utilization of its...
