Abstract:

During year one of AFOSR 860031, significant progress has been achieved in I the main thrust area of ultrafast physics in microstructures and alloys semiconductors - regarding carrier dynamics using picosecond photoluminescence kinetics of 2D Gallium ArsenideGallium Aluminum Arsenide QW on 2 to 50 pico second time scale dependence of electron temperature on well width in single Aluminum Indium GalideGallium Indium Arsenide QW determination of valence band discontinuity via optical transitions in ultrathin QW high density electron-hole plasma energy relaxation and rapid expansion ultrafast carrier recombination relaxation in magnetic semiconductor and emission and relaxation dynamics in optical deformation semiconductor Cadmium Sulfur Selenide alloy glasses and in II ultrafast pulse propagation in dielectrics and semiconductors - regarding the observation of induced spectral broadening in Zinc Selenide and BK-7 glass.
