Photoemission Orbital Tomography

Caption

In time-resolved Photoemission Orbital Tomography, a pump laser pulse (blue) generates a bound electron-hole pair (exciton) in the organic semiconductor material alpha-sexithiophene. The subsequent high-energy UV laser pulse ejects an electron from the exciton, and the energy and direction of this electron are measured.
