What is a quantum dot?

Quantum dot is a particle that has an approximate size of one nanometer that has the characteristics of the display of the semiconductor. The semiconductor is a solid material that has a certain amount of electrical conductivity. Silicon is one of the most popular materials used to create a quantum dot. These qualities could have some advantages for people, including, but not only, energy production and light. Unlike some forms of nanotechnology, a quantum dot is not theoretical. Was created in the real world settings.

The key to the quantum dot is in electrons. Electrons occupy one of the two belts in the material crystal. By providing the right stimuli, an electron or perhaps more than one can be encouraged to move from one band to another. As it moves from one zone to another, it creates a hole, which is positive. Together, the hole and electron are referred to as exciton.

electron and hole in exciton usualcage keep the distance apart. This is called the radius of Exciton Bohr. However, if the crystal is reduced, this gap thrives. Once this happens, it changes the ability to absorb and emit energy. At this point, a quantum dot is created. Different colors can be obtained by reducing or increasing the size of the quantum dot.

Quantum Dot has a number of different applications. Multiple quantum dots can be used as light -emitting diodes, cells dyeing for observing science of life, even inks that can help to look at counterfeiting. Another security application that can soon be implemented is luminescent dust that could be used to monitor offenses in limited areas.

Like optical fibers, quantum of dots can also be used to transfer data. Some estimates indicate that data transfer using quantum dots could increase a million times compared to standard Ethernet connections.

Although it is some of the top applications, they are hereAlso more secular. Quantum dots can be used as a light source in buildings or even computer screen lighting.
