Exciton Bohr radius can be defined as the separation distance between electron and hole. We all know that the charge carriers can move freely in bulk semiconductor, thus the...

d holes determine their effective size and are referred to as the electron ae and hole ah Bohr radii. As for all charged particles, there are Coulombic interactions between the electrons and holes, and the strength of these interactions determine if the electr.

The exciton Bohr radius is given by the formula 7: ε r = dielectric constant (relative permittivity) m = mass; μ = reduced mass; a b = Bohr radius (0.053 nm)

The radius of the exciton (the distance between the electron and hole) can be calculated using the exciton Bohr energy formula: Where a H is the Bohr radius. You can also measure exciton binding energy experimentally.

1997年3月15日 · Incorporating the band structure of the material, we calculate the corrections to this simple picture arising from the fact that the exciton Bohr radius is comparable to the lattice constant.

2006年9月1日 · The Bohr radius of a semiconductor exciton provides a reference as to the exciton size in the bulk. Size-tuning of properties in QDs is attributed to confinement of the exciton in a nanocrystal...

Exciton Bohr radius can be expressed as: where, εr is the dielectric constant (relative permittivity), m is the mass, μ is reduced mass, and ab represents the Bohr radius (~0.053 nm). Confinement Energy

The key parameters of an exciton include its effective masses m exc and reduced mass μ exc, Bohr radius a B, binding energy E B, and oscillator strength, which will collectively affect the properties of polaritons, such as the nonlinearity, operating temperature, and polariton mode splitting. Excitons and polaritons are stable if the exciton ...

elaborate how the any empirical re-definition of Bohr exciton radius may affect the mean free path of exciton-exciton collision and the basic understanding of MEG/CM. We will argue in favor of a minimum size cut-off of MEG/CM as a result of significant reduction of collisional

6 天之前 · Our analysis connects this transition to the exciton’s spin-controlled effective quantum confinement, supported by the exciton’s dynamics. ... featuring a Bohr radius of 0.7 nm and 2.5 nm ...
