Abstract :
Summary form only given. We present results of a new investigation of ultrafast dynamics of optically excited carriers in the technologically important II-VI semiconductors ZnTe and CdTe. We discuss the effects of the two-photon absorption process in detail, and address the recombination/trapping dynamics of the carriers subsequent to the initial energy relaxation.
