Mesoscopic physics is a subdiscipline of condensed matter physics that deals with materials of an intermediate size. These materials range in size between the nanoscale for a quantity of atoms (such as a molecule) and of materials measuring micrometres. [1] The lower limit can also be defined as being the size of individual atoms.
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
A bio-nano generator is a nanoscale electrochemical device, like a fuel cell or galvanic cell, but drawing power from blood glucose in a living body, much the same as how the body generates energy from food. To achieve the effect, an enzyme is used that is capable of stripping glucose of its electrons, freeing
The nanoscale transistors and nanoscale mechanical components (on a separate die) are integrated on the same chip package. [1] Nanoelectromechanical systems (NEMS) are a class of devices integrating electrical and mechanical functionality on the nanoscale.
Nanoelectronics is a multidisciplinary area composed of quantum physics, device analysis, system integration, and circuit analysis. [13] Since de Broglie wavelength in the semiconductors may be on the order of 100 nm, the quantum effect at this length scale becomes essential. [13]
Silicon photonics is a silicon-based subfield of nanophotonics in which nano-scale structures of the optoelectronic devices realized on silicon substrates and that are capable to control both light and electrons. They allow to couple electronic and optical functionality in one single device.
A nanostructure is a structure of intermediate size between microscopic and molecular structures.Nanostructural detail is microstructure at nanoscale.. In describing nanostructures, it is necessary to differentiate between the number of dimensions in the volume of an object which are on the nanoscale.
When these devices are fabricated using semiconductor nanowires as the transistor element the binding of a chemical or biological species to the surface of the sensor can lead to the depletion or accumulation of charge carriers in the "bulk" of the nanometer diameter nanowire i.e. (small cross section available for conduction channels).
