INTRODUCTION: Nanomaterials describe (in principle) ingredients whose single units (in at least one dimension) are between 1 and 1,000 nanometers (10 to 9 meters), but are generally between 1 and 100 nm (the usual definition of the nanoscale[1]). The study of nanomaterials is a field that takes a materials science-based approach to nanotechnology. He studies ingredients presenting morphological landscapes at the nanometric scale, and exclusively those which have particular properties limiting their nanometric extent. The fine structure of foraminifera and germs (capsid), the wax crystals covering a lotus leaf, spider and mite silk,[ 2] the "spatulas" located under the gecko's legs, certain scales of butterfly wings, natural colloids (milk, blood), horny materials, paper, fibers, mother-of-pearl, corals and even our own bone atmosphere are all natural plant nanomaterials. Multidimensional nanomaterials, such as thin films and engineered faces, have long been developed and used in fields such as electronic device creation, chemistry, and engineering. In the silicon integrated circuit industry, many devices rely on thin films for their operation, and controlling film thickness at the atomic level is routine. Monolayers (layers one atom or molecule deep) are also commonly made and used in chemistry. The formation and properties of these layers are reasonably well implied from the atomic level, even in quite complex layers (like lubricants). Progress is being made in controlling surface composition and smoothness, as well as improving films. Engineered surfaces with tailored properties such as high surface area or specific reactivity are routinely used in a range of applications such as in fuel cells and catalysts. The large surface is...... middle of paper...... the energy bands stop crossing each other. Due to their fundamental wave nature, electrons can quantum tunnel without reflection between two closely aligned nanostructures, and if a current is applied between two nanostructures that aligns the discrete dynamism levels in the DOS, reverberant tunneling appears, which which briefly increases the tunnel current. .Optical properties:1. In small nano-nodes, the effect of full dimensionality on the electronic edifice has the most philosophical effect on the energies of the principal occupied molecular orbital (HOMO) which is the valence band and the disused molecular orbital the lowest (LUMO), essentially the transport band.2. Optical emanation and adsorption occur when electron exchange occurs between these two states.3. Semiconductors and many metals show large changes in optical assets such as color, depending on the size of the elements..
