English dictionary definition of exciton. An electrically neutral excited state of an . Room-temperature electrical control of exciton flux in a van der . We explain underlying physics of exciton -polariton formation in a semiconductor microcavity. Here we report the existence of efficient exciton – exciton annihilation, a four-body interaction, in this material.
The formation energy of the lowest exciton state increases from 1. Exciton – exciton annihilation was . V with decreasing the dimensionality in the crystal structure, from the transfer . We studied exciton transport in the ramp for different excitation powers Pex and cryostat temperatures Tbath. Photo-induced charge transfer studies of polymer-Cmixtures indicate that the electron and hole are easily separated implying a small exciton binding . We have studied the effect of hydrostatic pressure on the confined exciton in a spherical core–shell quantum dot. Using a simple variational . The mysteries of exciton dynamics in molecular crystals and their effect on optical properties, luminescence, and photocurrent.
