Figure 3.12 Hot phonon bottleneck to slow hot-electron cooling in QWs. At high light intensity, hot electrons produce hot phonons which can reheat electrons via phonon absorption to keep them hot. Pioss is power loss per electron.

QWs, the phonons are confined in the well and they exhibit slab modes (Campos et al, 1992), which enhance the hot phonon bottleneck effect.

The free-exciton collision model [61] proposes that, during the PL measurement, the excitation laser heats the free excitons which then collide with the boundaries of the nanometer-sized fragments. The PL blueshift originates from the activation of hot-phonon-assisted electronic transitions, instead of quantum confinement.
