Focused-ion-beam writing of electrical connections into platinum oxide films
A focused Ga+ ion-beam (FIB) writing system has been used to directly change an insulating platinum oxide film into a conducting film with a dose in the order of 1014 Ga + /cm2 at 30 keV ion energy. T...

Experiments and theory have so far demonstrated that single molecules can form the core of a two-terminal device. Here we report first-principles calculations of transport through a benzene-1, 4-dithiolate molecule with a third capacitive terminal (gate). We find that the resistance of the molecule rises from its zero-gate-bias value to a value roughly equal to the quantum of resistance (12.9 kOmega) when resonant tunneling through the pi* antibonding orbitals occurs. ©2000 American Institute of Physics.

  24. This charge has been calculated as the difference between the charge of the total system and the charge of the bare electrodes, integrating between the right and left Fermi levels in a volume of 8.3×8.3×11.9 Å3. This volume comprises most of the potential induced by the presence of the molecule.
