Strands and cylinders of nanowires with structure (silicon/germanium) for possible applications in electronic energy

Note: strings and tiny cylinders of nanowires with structure (silicon / germanium)  for possible applications in energy, electronics, Optics and other fields are used.

Nanowires (Si Silicon / Germanium Gi) , narrow structures whose diameter is only a few billionths of a meter but thousands or millions of times They are longer. They exist in various forms - made of metals, semiconductors, insulators and organic compounds - and are used in the fields of electronics, energy conversion, optics and chemical sensing. Due to being very thin, nanowires with structure (Si Silicon / Germanium Gi) are basically one-dimensional are. Nanowires are quasi-one-dimensional materials, "their two dimensions are on the nanometer scale." This one-dimensionality confers distinct electrical and optical properties.For one thing, this means that the electrons and photons in this nanowire "confined quantum effects" experience " However, unlike other materials that produce such quantum effects, such as quantum dots, the length of nanowires allows them to communicate with other macroscopic devices and the outside world. /span>

The structure of a nanowire is so simple that there is no room for defects and electrons pass without hindrance. This is a big problem with conventional crystalline semiconductors, such as those made from silicon wafers: defects are always present in those structures, and those defects interfere with the flow of electrons. Furthermore, materials that usually do not mix easily can be assembled into nanowires. For example, layers of silicon and germanium, two very widely used semiconductors, "are very difficult to grow side by side in thin films." "But in nanowires, they can be grown without any problems." Furthermore, the equipment required for this type of vapor deposition is widely used in the semiconductor industry and can easily be adapted for the production of nanowires.

Conclusion :

Strands and cylinders of nanowires with structure (silicon / germanium)  for possible applications in energy, electronics, optics and Other fields are used.
