Ultrafast Phase Relaxation of Excitons via Exciton-Exciton and Exciton-Electron Collisions

Physical Review Letters, 1986
The ultrafast relaxation of excitons in GaAs, coherently excited by a short optical pulse and subjected to collisions with free carriers and noncoherent excitons which are independently created by a second synchronized light pulse, is studied directly in the time domain by a probing of the excitonic phase coherence.

Excitons, or No Excitons, That Is the Question

physica status solidi (a), 2000
We study the population of excitons in GaAs/AlGaAs quantum wells in the time span between optical excitation and optical recombination. We distinguish between 1s excitons and free electrons and holes by tracing the electron–hole exchange energy and thereby the overlap of electron and hole.

Universal Inverse Scaling of Exciton–Exciton Annihilation Coefficient with Exciton Lifetime

Nano Letters, 2020
Be it for essential everyday applications such as bright light-emitting devices or to achieve Bose-Einstein condensation, materials in which high densities of excitons recombine radiatively are crucially important. However, in all excitonic materials, exciton-exciton annihilation (EEA) becomes the dominant loss mechanism at high densities. Typically, a
