Abstract:
Two-dimensional semiconductors are ideal model systems for investigating the dynamics of the electron-phonon interaction under spatial confinement of electronic excitations. In this contribution, the simultaneous quantum dynamics of electrons and phonons on ultrafast timescales is theoretically addressed. Typical examples include the ultrafast electron transfer at silicon surfaces, optical intersubband transitions in doped quantum wells, and non-equilibrium phonon generation in graphene.
