The distance between the electron in the conduction band and its hole in the valence band is called the Bohr radius. The diameter of a QD is in the same order as its exciton Bohr radius ...

"We attribute this suppression to a reduced exciton Bohr radius and exciton diffusion coefficient, as extracted from optical ...

This loss of efficiency at high current densities has been linked to high levels of interaction between excitons, which cause a process known as exciton-exciton annihilation (EEA). Essentially, the ...
