    Ultrafast Phase Transition Dynamics in GeSb Films, at Optical Society of America Annual Meeting, Optical Society of America (Providence, RI, USA), Thursday, October 26, 2000:
    We measure the dielectric function of thin a-GeSb films over a broad energy range (1.5 - 3.5 eV) with a time resolution of 70 fs after the excitation with an ultrashort laser pulse. The results reveal an ultrafast transition to a new non-thermodynamic phase which is not c-GeSb as previously believed.
    Ultrafast Phase Transition Dynamics in GeSb Films, at Nonlinear Optics 2000, Optical Society of America (Kaua'i, HI, USA), Tuesday, August 8, 2000:
    We measure the femtosecond time resolved dielectric function of a-GeSb after excitation with an ultrashort laser pulse. The results reveal an ultrafast transition to a new non-thermodynamic phase which is not c-GeSb as previously believed.
