As we approach the single molecule scale, we are fast approaching the the limits of miniaturizing information. The star of silicon microelectronics has been the field effect transistor (FET) which acts as a voltage-controlled current switch, and a bit is represented by the on/off states of a pair of n-channel and p-channel FETs. However, porting FETs to the molecular scale has its limitations. ...

Josephson transport through a single molecule or carbon nanotube is considered in the presence of a local vibrational mode coupled to the electronic charge. The ground-state solution is obtained exactly in the limit of a large superconducting gap and is extended by variational analysis. The Josephson current induces squeezing of the phonon mode, which is controlled by the superconducting phase ...

Nowadays carbon nanoparticles are applied on the island of single electron transistor and Nano-transistors. The basis of single electron devices (SEDs) is controllable single electron transfer between small conducting islands. Based on the important points in quantum mechanics, when a wave passes through several spatial regions with different boundaries, the wave function of the first region di...

In recent years several suggestions how to set up a single electron transistor have been made [1,2,3,4]. The development of new methods to contact molecules or molecule-like systems and control the electron transport through them [5,6,7] is a major issue in the promising field of molecular electronics [8,9]. The conventional setup of such a transistor requires a gate in order to trigger via the...

The electronic conduction of a novel, three-terminal molecular architecture, analogous to a heterojunction bipolar transistor is studied. In this architecture, two diode arms consisting of donor-acceptor molecular wires fuse through a ring, while a gate modulating wire is a conjugated wire. The calculated results show the enhancement or depletion mode of a transistor by applying a gate field a...

The electronic conduction of a novel, three-terminal molecular architecture, analogous to a heterojunction bipolar transistor, is studied. In this architecture, two diode arms consisting of donor-acceptor molecular wires fuse through a ring, while a gate modulating wire is a pi-conjugated wire. The calculated results show the enhancement or depletion mode of a transistor on applying a gate fiel...
