Stability of Charged Exciton States in Quantum Wires

چکیده
We show that the order of energies of negative (X ) and positive (Xþ) trions in quantum wires is determined by the relative electron and hole lateral confinements. For equal electron and hole confinement, Xþ has a larger binding energy, but a small imbalance towards a stronger hole localization changes the order of the X and Xþ recombination lines in the photoluminescence spectrum.

Semiconducting polymer quantum wires
Semiconducting polymer heterostructures with strong two-dimensional quantum confinement of excitons are prepared by self-assembly of two conjugated polymers in binary blends. Exciton confinement effects in the semiconducting polymer quantum wires were observed at room temperature by photoluminescence excitation and photoluminescence spectroscopies and by electric field-induced photoluminescence...
متن کاملFlat-band excitonic states in Kagome lattice on semiconductor surfaces
Recent surface techniques to fabricate and arrange quantum wires on the semiconductor surface have enabled to synthesize the artificial two-dimensional lattice systems such as square and triangle lattices. For example, C. Albrecht et al. produced a square lattice by arranging InAs wires on GaInAs (001) surface and showed that a butterfly energy spectra is seen in the case of applying the magnet...
متن کاملExciton states and optical absorption in quantum wires under laser radiation
We analyze the excitons states in a quantum wire under intense laser radiation. Electrons and holes are confined by the parabolic potential of the quantum wire. An exactly solvable model is introduced for calculating the exciton binding energy, replacing the actual Coulomb interaction between the electron and the hole by a projective operator.
متن کاملFine structure of highly charged excitons in semiconductor quantum dots.
An exciton in a symmetric semiconductor quantum dot has two possible states, one dark and one bright, split in energy by the electron-hole exchange interaction. We demonstrate that for a doubly charged exciton, there are also two states split by the electron-hole exchange, but both states are now bright. We also uncover a fine structure in the emission from the triply charged exciton. By measur...

Thermal variation of PL peak energy of undoped nitride semiconductor quantum well shows a successive red-blue-red shifted emission (S-shaped behavior). This behavior has been attributed to the localization of excitons at the energy minima induced by the potential fluctuations in the quantum well structure and/or interface roughness. The S-shaped behavior of PL peak position, the thermal variati...
