I/V characteristics recorded in mechanically controllable break junctions revealed that field emission transport is enhanced in single molecule junctions as the gap size between two nanoelectrodes is reduced. This observation indicates that Fowler-Nordheim tunneling occurs not only for intermolecular but also for intramolecular electron transport driven by a reduced energy barrier at short tunn...

We study heating and heat dissipation of a single C(60) molecule in the junction of a scanning tunneling microscope by measuring the electron current required to thermally decompose the fullerene cage. The power for decomposition varies with electron energy and reflects the molecular resonance structure. When the scanning tunneling microscope tip contacts the fullerene the molecule can sustain ...

As single electron tunneling technology based threshold logic gate uses less no of tunnel junctions so it reduces the size of Boolean logic gate compare to single electron tunneling based logic gate and single electron transistor based logic gate. The design and simulation of a 4:1 multiplexer based on buffered threshold logic gate is presented in this paper. The logic operation is verified usi...

Random Telegraph Signals (RTS) in transport current through a conduction channel of a Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) are known to be related to charging and discharging of a single impurity due to electron tunneling between the impurity and the channel. The phenomenon provides a unique example where a single electron tunneling can be explicitly monitored. Recent expe...

Zeeman splitting of the ground state of single impurities in the quantum well of a resonant tunneling heterostructure is reported. We determine the absolute magnitude of the effective magnetic spin splitting factor g ' for a single impurity in a 44 Å Al0.27Ga0.73AsyGaAsyAl0.27Ga0.73As quantum well to be 0.28 6 0.02. This system also allows for independent measurement of the electron tunneling r...

This paper investigates the implementation of Periodic Symmetric Functions (PSF) in single electron tunneling technology. First, we discuss the procedure of expressing arithmetic and logic operations as generalized PSFs. Second, we propose a building block that performs a multiple input PSF. The block we propose can be used for the computation of any function that is or can be expressed as a PS...

Single-electron transistors SETs are often discussed as elements. A single-electron transistor consists of a small conducting island coupled to source and.Single-electron transistor SET is a key element in our research field where.
