Abstract

Pollen has various effects on human health and the environment. To understand phenomena behind atmospheric pollen transport and hence improve pollen forecasts, vertically resolved optical properties and geometrical characteristics of the pollen distribution need to be studied. Lidar measurements and especially the particle depolarization ratio have been found to be an excellent tool to track pollen grains. In this study we present first results of atmospheric pollen characterization based on a 11 days period of birch and spruce pollination events. [ABSTRACT FROM AUTHOR]

Abstract

Temperature dependence of hole and electron spin relaxation times in both InAs quantum dots (QDs) and quasi-two-dimensional (2D) monolayers has been investigated experimentally using time-resolved photoluminescence (TRPL). The results show that hole spin relaxation time is long enough to be comparable with that of electrons in the quasi-2D InAs structure, but is one order of magnitude smaller than the electron spin relaxation time in QDs structure. It is shown that both hole and electron spin relaxation times decrease monotonically with increasing temperature for InAs QDs, but show non-monotonic temperature-dependent behavior for the quasi-2D structure. Different spin relaxation mechanisms responsible for spin relaxation in the two structures have been discussed. [ABSTRACT FROM AUTHOR]
