For example, the electron volt is not the SI unit of energy, and yet it is commonly used, the same with the Bohr radius as a unit of length.

A'strong confinement regime'is defined as the quantum dots radius being smaller than both electron and hole Bohr radius,'weak confinement'is given when the quantum dot is larger than both.
23.
As the thickness of silicon-based nanostructures reduces below the effective Bohr radius ( about 9 nm, in silicon ) the quantum efficiency of light emission from this material increases owing to the quantum confinement effect.
24.
The significance of Haas'work lay in the establishment of a relationship between Planck's constant and atomic dimensions, having been first to correctly estimate the magnitude of what is today known as the Bohr radius.
25.
Mott argued that the transition must be sudden, occurring when the density of free electrons N and the Bohr radius a _ H satisfies N ^ { 1 / 3 } a _ H \ simeq 0.2.
26.
Plugging this in for v / c for the relativistic mass one finds that m rel = 1.22m e and in turn putting this in for the Bohr radius above one finds that the radius shrinks by 22 %.
27.
Quantum dots are semiconducting particles that have been reduced below the size of the Exciton Bohr radius and due to quantum mechanics considerations, the electron energies that can exist within them become finite, much alike energies in an atom.
28.
A consequence of these constraints is that the electron will not crash into the nucleus : it cannot continuously emit energy, and it cannot come closer to the nucleus than " a " 0 ( the Bohr radius ).
29.
:Assuming that by size you do indeed mean size, as oposed to mass, the size of atoms is governed by the Bohr radius which is inversely proportional to the speed of light . talk ) 14 : 39, 26 July 2011 ( UTC)

For semiconductors in which electron and hole radii are markedly different, an'intermediate confinement regime'exists, where the quantum dot's radius is larger than the Bohr radius of one charge carrier ( typically the hole ), but not the other charge carrier.
