As a definite example we will show how it is possible to control the magnitude and the direction of a photoinduced current, in a symmetric semiconductor and in a quantum well, relying solely on the coherence of the illuminating source, i.e. without the introduction of a bias voltage. If time permits we will turn to a much more espectacular example: laser assymetric synthesis and laser distillation of racemic mixtures of enantiomers. +---------------------------------+ | Ignacio Franco | | ifranco@chem.utoronto.ca | | | | Chemical Physics Theory Group | | Department of Chemistry | | University of Toronto | | 80 St. George Street | | Toronto, Canada M5S 3H6 | | Tel +1-416-9468046 | | Fax +1-416-9785325 | | Cel +1-647-2959645 | +---------------------------------+
