Summary
| Description |
English: Carrier relaxation probed with 2D electronic spectroscopy. a–c 2DES maps for time delays t 2 of a 0 fs, b 80 fs and c 500 fs for an excitation density of 2 × 1018 cm−3. The diagonal of the 2DES maps is indicated with orange lines. d Schematic illustration of carrier relaxation processes. Initially, a non-thermal carrier energy distribution is excited. After undergoing carrier-carrier scattering, carriers form a thermalized distribution with a temperature higher than the lattice. Through carrier-phonon scattering, the carriers subsequently cool down until they reach an equilibrium with the lattice temperature |
