Nanoscale electronic devices

These significant findings form the basis of a set of design principles for the construction of molecular photovoltaic cells and other nanoscale electronic devices in which the control of both the rate and directionality of ET processes is an essential requirement. The successful construction of an artificial light-driven proton pump, based on principles of long-range ET processes illustrates the promise of this approach.1501...

Such controlled motion might become even more important, if one realizes that a bistable, controllable rotaxane might be useful as a nanoscale electronic device. One state would then be the "0", the other would represent the 1" state of one bit of a computer memory. Even if we have a long way to go before using these molecules as reliable functional units in electrical circuits minimized to nanometer dimensions, it seems to be of great promise and such promise demands the intense study of ways to synthesize these molecules and the detailed examination of their properties. 

As already described in Section 12.1, the construction of nanoscale electronic devices from conducting biopolymers remains a challenging task. DNA represents a superior material for this research by moving away from the natural biological... 

In the paper we continue the researches started in [1] where the possibility of existence of T-junctions of (6,6) CNT with graphite monolayer was shown. Here some samples of T-junctions of carbon zigzag and armchair CNTs are investigated. Experimental and theoretical aspects of perspectives of using of CNT T-junctions as elements of future nanoscale electronic devices are considered earlier in [4-10]. 

Single-walled carbon nanotubes are known to possess extraordinary strength.138 Mechanical properties of BN nanotubes would be worthy of exploration. Unlike carbon nanotubes, BN nanotubes are predicted to have stable insulating properties independent of their structure and morphology. Thus, BN tubes can be used as nano-insulating devices for encapsulating conducting materials like metallic wires. Filled BN nanotubes are expected to be useful in nanoscale electronic devices and for the preparation of nano-structured ceramics.

Metallofullerenes will also become an important nanostructured material for future nanoscale electronic devices, because the band gaps of endohedral metallofullerenes, for example, can be varied between 1.0 and 0.2 eV depending on the fullerene size, the kind of metal atom(s) as well as the number of metal atoms encapsulated. 

PANI nanowires are ID nanostructures which are very interesting from the nanotechnology point of view, due to their potential use in sensors and nanoscale electronic devices. DNA can be considered as an anionic polyelectrolyte that can behave as a template for PANI enzymatic polymerization in solution [20]. Double stranded DNA can be attached to aminated surfaces by electrostatic self assembly, providing a linear template for further aniline electrostatic assembly. By using this method followed by enzymatic polymerization of the assembled aniline, Ma et al. [69] and Nickels et al. [70] showed that stretched DNA molecules were able to template the enzymatic synthesis of PANI nanowires, according to the mechanism showed in Figure 8.7.

Poly(phenylenevinylene) has been considered for many different applications due to its importance in nanoscale electronic devices. One such application is the search for efficient light emitting diodes. This property is the result of the electrooptical effect and constitutes an important area of modern research in theory as well as experiment. The efficiency of the nonradiative...
