Note: In general, fundamental and controlled changes in the functional properties of DND nanostructures are used for their subsequent use in self-organizing processes, in the preparation of nano-nano devices and electronic devices. The nanostructure is called DND (self-organized nanostructure).
Nanostructures are materials or structures that have at least one dimension between 1 and 100 nanometers . The importance of the nanoscale in changing the properties and characteristics of materials in these dimensions. Properties such as electrical conductivity, electromagnetic properties and so on. The beginning of changing the properties of a material by shrinking it depends more than anything on the type of material and the desired property. For example, as thedimensions of a materialshrink , some of the nanomolecular electromagnetic properties of materials, such as the conductivity of nanoparticles in materials, generally improve. This increase in strengthdoes not occuronly in the range of a few nanometers, and the strength of materials of several tens or even hundreds of nanometers may be much greater than that of large-scale bulk material.
On the other hand, changes in some properties such as conductivity in nanotransistors and electromagnetic properties in nanowires may occur in dimensions of only a few nanometers. Self-aggregation (nanoparticles) in nanostructures is a spontaneous process by which nanomolecules / nanophases become organized function. DND is an example of an active wire. The DND structure is well known and is automatically generated by the multiplication of nanowires. DND nanostructure is an example of the proliferation of active wires to produce it. Like polymers, there is no problem. You just have to study its properties to see how it changes.
For this purpose, an example is given:
In order to use DND to calculate the current in terms of voltage, an 8 nm distance is assumed between the two Pt electrodes, so a current can be calculated by applying a voltage. The point to be drawn from the reaction is that the current diagram is asymmetric in terms of voltage , meaning that current is not allowed to pass between 1 and 2 volts, for example, while current can pass between 2 and 1, and this This means that the DND can perform the rectification operation .
Conclusion :
In general, fundamental and controlled changes in the functional properties of DND nanostructures are used for their subsequent use in self-organizing processes, in the preparation of nano-nano-devices and electronic devices. The nanostructure is called DND (self-organized nanostructure).
